Penile Erection

August 18, 2015

I noticed that I did not yet post anything on penile erection. In fact this is a rather „big theme“, however, there are two reasons why it didn´t show here all the time.

For one it is a function we take for granted, and it just so much belongs to being sexually active that it seems not to be necessary to make it an issue. On top of that readers here know that orgasm and ejaculation can be achieved without erection.

Yet admittedly erection becomes an issue quickly when it does not occur as desired or needed (in sexplay). Now, while my blog is supposed to serve readers in finding arousal and sex-positive enlightenment, it will thus not make problems in connection with sexuality a subject of deeper discussion!

A second reason for not covering this topic until now is that the function of penile erection, as fascinating and arousing it shows, is a rather sophisticated anatomical process that, would it be explained in detail, would make readers move on promptly.


Just for the sake of cumpleteness let me briefly inform you about the three types of erection (it gets a bit anatomical now). I take this info from a paper by the Department of Urology, University of California School of Medicine, San Francisco, California issued in 1999:

The three types of erection are: psychogenic, reflexogenic and nocturnal.

Psychogenic erection is a result of audiovisual stimuli or fantasy. Impulses from the brain modulate the spinal erection centers to activate the erectile process.

Reflexogenic erection is produced by tactile stimuli to the genital organs. The impulses reach the spinal erection centers; some then follow the ascending tract, resulting in sensory perception, while others activate the autonomic nuclei to send messages via the cavernous nerves to the penis to induce erection. (This type of erection is preserved in patients with upper spinal cord injury.)

Nocturnal erection occurs mostly during rapid-eye-movement (REM) sleep. The mechanism is as yet unknown.

I don´t know if the last sentence still is valid? Within human sexuality we continually find aspects well worth to further investigate scientifically. Until then biological functioning, in particular connected to (male) sexuality, may appear mysterious, stunning and highly stimulating, just as penile erection does. Enjoy it within you (the sensations of swelling), enjoy it visually, in nature or in that fantastic animated gif above. Or check out this brief clip of a semi erect cock with unretracted foreskin (and a thread of precum reaching down and out of frame) growing in a fast forwarded scene. – Note that both above featured erections fall under the psychogenic type of tumescence.

At last I need to address an aspect that touches the wonderful shapeshifting capacity of human penises!

Every specimen is different, in design and in size. When we think of size we need to consider the different erectile states a cock can transform into. We find that every wand has a certain individual range of shapeshifting (the margin between flaccidity and full erection). And we notice that this range can be impressive (big shift) or less spectacular (minor shift).

thick flacid

There is a catchphrase asking for those differences a man can feature: is he a grower or is he a shower?! If he is a grower his penis will shift shape largely while growing erect. If he is a shower his penis will shift shape not substantially from the flaccid to the erect state.

In this context, the term shower is targeted on men with a large cock in the flaccid state! The guy in the anim-gif I do consider being a grower, although his first-rate member is already quite large in the flaccid state. But that exactly is the beauty of this hot gif! As witnessing erection basically always is!!

big flacid

Don´t miss to visit this site to check on many different penises all being pictured in their flaccid and erect states (great comparative study/database). Click the button soft-hard in the top-bar of the page!

Before you leave for the Soft-Hard Gallery don´t forget to answer the current matching poll! 🙂 Thanks!

    Great, I was thinking about this blog just the other day. And low and behold you come forth with another stunning post!!
    I did answer your current poll too 😉 as a grower.

    I couldn’t say it any better “But that exactly is the beauty of this hot gif! As witnessing erection basically always is!!”
    Very hot indeed and the other two pictures are also great!!

    You put this great topic into laymen terms that pretty much anybody could understand. I finished reading it and was disappointed that i was done with it. I wanted more to read. So very interesting! But was still very happy that I was able to learn something new from your blog again!
    I do thank you for this and the time you put into it!

      Thanks for your kind praise yet again! Such keeps me going, what can I say. 🙂

      It´s been overdue to place another post. You will know that I want to publish twice a month (I said so in the comments somewhere), it just may not always be a text with “news value” such as this one (as humble as this may be). And – I also mentioned this – a lot of ground has already been covered…
      But continue to expect a steady input at the noted pace, I´ll try my best!

        No need to say anything! Just keep up the great work!
        I know that you’re probably busy with life just like rest of us. So don’t feel so bad that you don’t update as often as you’d like. Me ( I’m sure others feel the same) personally would rather you take your time with each post and make them stellar, than rush them.

        PS: by the way, I think I could look at that second cock picture pretty much all day!

      • nandisa Says:

        Well, that pretty much describes the current status quo! 😉

        Yeah, that 2nd cock is a flaccid beauty indeed (and now we wonder about his looks in the erect state, at least I do)! He could be a shower, but you never can be sure until… 🙂

    Nandisa: I am not sure that a detailed description of the erection process would cause readers to flee, particularly since we come to this blog for just this type of information, in addition to the hot pics and videos that illustrate your various points.

    It fascinates me that the nocturnal erection is a physiologic mystery. However, having the regular pleasure of awaking to that very type, I am quite content for it to remain one.

    PS grower here too.
    PPS as usual the gif is incredible.

      Thanks for your input as well, Tom.

      Maybe you are right (referring to your first paragraph). That´s why I updated the post and added (linked to) a brief pdf about the mechanics of erection, which should cover that part of the reaction (I found this text, enhanced it, so less work 😉 ) in non-repelling lingo.

      For your convenience: find the file via this link!

    🙏 Amen to that, Chas.

    That last photo looks wonderful, a great angle! While i’m a grower myself, the photo is not far from my own, i’m like that after sex, soft, but still quite full and girthy and the scrotum relaxed and hanging. Add a thin layer of body lotion or olive oil and i’m there! 😀
