"Long penises and mushroom-heads are better" says SCIENCE.

[EnTaro]

Secrets of the Phallus.

I'll paraphrase, but a basic understanding of evolution is necessary.

The adaptiveness of a long penis was obvious - you can go deeper and ejaculate closer to the cervix, increasing chances of fertilisation (babies!).

More interestingly, another seperate idea is that mushroom-shaped heads (heads where the "coronal ridge", the distance from the base of the glans to the top of the shaft) are more likely to result in fertilisation because they pull other men's semen out of your lover's vagina.

That's right. Next time you're bragging about your bulbous glans, remember that nature gave you that to scoop out other men's jizz. Sigs should now include length, girth, and distance from the tip of the glans to the shaft.

What if you are gay?

Then you scoop out something else.:tongue:

What if you are gay?

Then you aren't reproducing so move on.

Other men ?

Interesting theory

Looks like I've been built for reproductive success then. And I don't even want kids. :tongue:

This is of course assuming the female has just been very recently inseminated by one or more other men. If that's not the case, then there is obviously no semen to scrape out and therefore no evolutionary advantage.

Fascinating theory about this adaptive evolution and I won't attempt to dispute it! I find myself wondering ,though , why after eons of this adaptive evolution, we do not all have foot long penises with a broad flaring glans?

 

[Wooly Mammoth]

I imagine a foot-long penis would not be popular with the ladies. "Ouch!"

Excellent :smile:

If some other guy's semen is already in there, then the glans would push it in further and would only scoop it out if it gets behind the head!

That's what I was thinking.

Sorry, to bring this up - I'm sure it will cause debate... but if you're uncut, then as you pull back your foreskin returns to its position covering the head. In that case, the coronal ridge is covered and scoops out nothing.

I'm uncut, and my foreskin doesn't do that. If there's enough lubrication and the pussy is tight, it stays pulled back even when coming out.

Good point about a thick head pushing semen in, though. I wonder what the researcher would say about that?
