Penis–Head

Our penises may come in all kinds of shapes and sizes, yet the basic design remains the same throughout all differences: our cocks appear as shafts crowned by a peculiar top, the glans or head (the whole penis is made of two different kinds of erectile tissue). This combination is unique and differs (overall in shape and size) very much from the penile design of even our closest living relatives (primates that is)! I personally adore the design of the human cock, particularly for its gorgeous head.*

So, only us human males feature such a distinctive mushroom-capped cock-head, which is connected to the shaft by the frenulum (the delicate tab of skin just beneath the meatus, as to be seen in the next couple of pics) on its underside. Probably the most significant design of the glans is the coronal ridge. The diameter of the „helmet“ where it meets the shaft is wider than the shaft itself. This results in the coronal ridge that runs around the circumference of the shaft. And here the question arises: Why is it like that? and What is that for?

According to evolutionary psychologist Gordon Gallup of the State University of New York at Albany, the human penis is literally an impressive “tool” [mind you in a different meaning of the term and how I used it in this blog]. Gallup’s research findings of studying the design of the human penis is a perfect example of “reverse-engineering”. This means that if we start with what we see today — the oddly shaped cock, with its bulbous head, its long, rigid shaft, and the coronal ridge — and work our way backward regarding how it came to look like that, the reverse-engineer is able to suggest a set of function-based hypotheses derived from evolutionary theory.

Now, it appears there’s a genuine adaptive reason that our cocks look the way they do. We must consider the evolution of our tools in relation to the human vagina. Magnetic imaging studies of heterosexual couples fucking reveal that the penis completely occupies the vaginal tract, and with full penetration does reach the woman’s cervix and lift her uterus. This combined with the fact that cum is expelled with great force, suggests that the male genitals are ment to release sperm into the uppermost portion of the vagina possible. Thus, in a theoretical paper published in the journal Evolutionary Psychology in 2004, Gallup and coauthor, Rebecca Burch, assume that,

“A longer penis would not only have been an advantage for leaving semen in a less accessible part of the vagina, but by filling and expanding the vagina it also would aid and abet the displacement of semen left by other males as a means of maximizing the likelihood of paternity.”

The “semen displacement theory” is the most intriguing part of Gallup’s research. Besides being a brilliant evolutionary theorist, he happens also to be a very gifted experimental researcher. In a series of studies published in a 2003 issue of the journal Evolution & Human Behavior, Gallup and a team of his students put the “semen displacement hypothesis” to the test using artificial genitalia. They even concocted several batches of realistic seminal fluid. Results from this study may not have “proved” the semen displacement hypothesis, but they definitely confirmed its principal points.

And how does the cum displacing work after all? Well, according to Gallup our cocks were sculpted in such a way that our tools would effectively displace the jizz of competitors from their partner’s vagina, a well-synchronized effect facilitated by the “upsuck” of thrusting during fucking. Specifically, the coronal ridge offers a special removal service by expunging strange cum. Gallup’s experiments showed, that the effect of thrusting would be to draw other men’s juices away from the cervix and back around the glans, thus scooping out the spunk deposited by a sexual rival.

After all, thanks to evolution for that we are equipped with such sophisticated organs making them the most beautiful and wondrous sexual entities throughout the animal kingdom. I love penis from head to bulb and crura respectively.

For a Closer Look (12) – Electro Edging

This clip illustrates how EES may extend/enhance an ejaculatory climax presumably after some time of electro-edging.

You see:
- the guy (rather his cock) instants before his ejaculation is triggered, you hear him breathing fast anticipating his climax. At sec 5 into the clip the first spill of milk is released (look closely and notice a drop of precum at his meatus). This is the beginning of about 10 strong contractions of his BC (and surely associated muscles). It appears that his cumproducing spasms grow in intensity, judged by the moaning we can hear. The guy doesn´t begin to heavily moan before his 3rd spill. Interestingly enough his ejaculatory reflex seems to happen rather slow and pronounced. And it lasts for almost the whole time of the clips duration. Instead of the usual pattern of an ejaculation with cum-shots we observe strong and distinct „penile spasms“ (i.e. BC and PC spasms) producing his milk as if pumped to the surface from a well.

clip still

The electro-stimulation applied right behind his corona at the sulcus does obviously trigger an initial emission followed by a series of strong muscular contractions pumping up his creamy milk. – Mind you that there are numerous possibilities to rig oneself with the different available gear. This one looks rather DIY.

It’s an unedited scene in fair quality (see still of clip) and with sound. It is 7.9 MB in size and running 39 seconds. The format of the clip is wmv.

Being Edged – What it Feels Like (1)

Read this story about a man giving feedback to his girlfriend while she is trying to edge him into a massive cumburst.

Her say in this color and His say in this color!

Me and my man have been a really good team when it came to sex. Most probably because we shared similar interests. I enjoyed to see him cum. It was not just to see his cock spurt, which most of the time it did spectacularly, it was rather to experience him cum. Because my man was very vocal (could afford that in an off the path house) he expressed his feelings without any inhibitions. So, after knowing him for years, that´s what we both enjoyed most: me making him cum, slowly, after some edging, after some fucking and lovemaking.

We had agreed upon that he was supposed to tell me in detail and on the spot while doing it, what he felt when he was filled with his milk and closing in on ejaculation. This may be the closest I could get to experiencing shooting cum, what I never will, because as a woman I lack a prostate and seminal vesicles. We had been fucking and giving each other head in the 69 fashion. He was a master in ejaculatory control, but eventually he just had to be increasingly alert not to have his reflex triggered. This is when edging begins. And one day I was to learn a lesson about his sensations and feelings while making him wander the edge.

So there he was lying on the bed, legs spread eagle, his cock throbbing, me sitting in front of his glistening wand and engorged shaved nutbag underneath.

What do you feel now?

I feel full. It´s a wonderful feeling. It´s not just from the blood in my boner and in my balls. It´s more, I now can sense that my glands are really filled up with my milk.

We called his semen milk or cream, following the consistency of his semen when he spilled it. Sometimes it was silky and viscid, we then called it cream. Most of the time it was more runny, then it was regarded milk. As a matter of fact often he provided both. And I was eager to consume it, I loved his sweet juices.

Ok, what are we going to do next?

Edging.

Yeah, I mean I want to know what you feel. What do I do to you while you report?

First massage my balls, but very tenderly.

I touched his swollen scrotum with my fingertips after I applied some walnut oil and began to slowly massage his balls.

Oh yes, fuck yes, this feels great. You know the skin is so sensitive it feels so good.

How exactly?

It feels liberating, aaaah, so sweet. And then my balls feel so full and as if they liked to turn and twist around inside of me. Now apply more grip, you can really knead them, carefully, but go for it.

I was doing as he said.

Oh yeah, oh yeah, aarrhhh this is goood!

What now?

Your massaging impact. God, you really have me by the balls. Gosh this feels like a good massage. It hurts here and there when you press a little too much or rub the balls. And yet it feels so good. Unfortunately I can not stand that very long, cause suddenly the effect is gone, as you know. Easy, easy – loosen up, please.

I was becoming light in my touch again. He was precumming heavy now and I reached for his honey with my free hand to catch and consume it.

This was so good. The internal pressure is really high now. I suggest you visit my prostate and vesicles next. Just lube your finger and penetrate me slowly.

I did after lubing his rear entry and my middle finger. I went in easily. This was exciting every time. I was moving slowly towards his glands.

Easy baby. My prostate is full of milk, I bet. You´re almost there. Easy now!

And then I was there and palpated the bulge which was his gland. It indeed felt engorged and somewhat tight.

Ahhh yes, there you are. – Watch my cockeye, I have the feeling your magic touch sent some cream to the surface, I can feel it traveling inside of me. This is fucking awesome!

I pressed a bit more and he moaned and a little gush of cream left his cock.

I feel so full, it makes me want to explode so badly. And yet all the sensations and having you in me are so wonderful. It´s like I don´t know what I want more, to blow or to edge. But sure we will keep me from cumming for a while. Just that the urge to shoot is so strong!

Carefully I began to massage his gland.

Fuck yesss! Watch for more, you just squeezed me right.

Yep, more cream was oozing out of him. It was mixed with precum and I catched it and had a first taste of his cum.

You taste sweet today my love.

Great. I hope I can give you loads of it today. Ouuhh, it is so enjoyable what you do, it is such a love thing what you do, this is so fucking intimate. God you are in me touching the very core of my sexual center. Try to milk some more out of me.

I tried to reach deeper. I felt the triangle where the seminal vesicles and ampullae meet the prostate. My man moaned.

to be continued…

For a Closer Look (11) – Repeated Emission

Here is another Closer Look of the guy cumming into a glas. I need not describe the setting as you may have had a look at the screenshots in the previous post. However, the following explanation tells about the context of this guys cum-release.

You see:
- the guy ready to release his milk into an empty glas. There is no precum visible at the cock slit. The guy has total control of triggering his emission(s), he is just holding his cock, no stroking required. His first ooze consists of thin and clear milk, you can see filaments being washed out. The clip fades to a second emission. This time the guy is oozing a larger volume of his now white, still runny milk. A few light touches of the corona of his cockhead trigger a third milky emission merging into a ejaculation with 7 rather modest gushes. The clip cuts to yet another round of milk-spill. Again emission is triggered and we observe a gush after the main ooze while it remains unclear if this was another ejaculation or a voluntary BC-contraction to push left milk out of his urethra.

This clip may be more a document of harvesting milk. Still it serves as a demonstration of an edgers ability to avoid PONR (for a while) and definitely split up the ejaculatory process into its components emission and expulsion. What you see represents edging between level 9 and 10 of the 10-Point-Scale of Sexual Arousal.

It’s an edited scene in fair quality (res. 320 x 240) and mute. It is 3.6 MB in size and running 1 minute. The format of the clip is mov.
