Well isn't this just dandy
 

Penis shape evolved to scrape other mens semen out of the vagina.

'"They found that the coronal ridge... could scoop out more than 90 percent of the cornstarch mixture (from the artificial vagina) with just one thrust, while a phallus with no coronal ridge only managed to remove 35 percent," New Scientist magazine said on Wednesday."

who the fuck researches this ?

:glugglug

"Gordon Gallup and researchers at the State University of New York in Albany showed in experiments using latex replicas.."

Try reading the article :winkwink:

not much of a article reader ;)

i say bullshit.

i'm betting it's all about suction.

What selection advantage (we're talking evolution here..) would "suction" confer?

Its all about getting your swimmers to the egg first.

cool. scoopin' semen.

cause if the lippy thing weren't there, all the swimmers would squish up the sides of the peenie when you shoot. the lippy thing acts as a suction seal dealy which keep da jizm inem.

that's my theory and i'm sticking to it! :thumbsup

hehehe...nice research

I'd like to know how they came up with that hypothesis in the first place. :Graucho

Someone was spending far too much time with a cock in their face and figured they may as well figure out a way to get paid for it.
One that the parents wouldn't have a heart attack over, that is.

I've paid close attention to my peeny for a number of decades now, and I'm certain that the only semen it ever dispelled was my own.

I would like to know who the fuck funds research for this shit. Tax dollars ? Gifts to the university ? I would like to get my hands on the people who waste that kind of money :feels-hot

And you wonder why costs for education keep going up up up like those penile thrusts......

It makes me wonder if it is some impotent old rich fuck try to get his rocks off by paying to stick paper cups into pussies

What a complete and totally bogus story. Research like that proves NOTHING about evolution.

Because I can wipe 90% of the shit off my ass after I take a dump with a single thurst, its evolutionary proof that toilet paper evolved to serve man.

you have toilet paper!... im still using corn cobs :Graucho

I believe it.
Its all about protecting our investment
