Not only size but shape matters !!!
 

It must be true a scientist said so!
This is the REAL reason MEN worry about their size, it's all about being the one to get the woman in the club !


LONDON (Reuters) - Size is usually more of an issue but the shape of the penis is also important because it evolved to dispel other men's semen, according to scientists in the United States.

Gordon Gallup and researchers at the State University of New York in Albany showed in experiments using latex replicas, an artificial vagina and a cornstarch mixture that the ridge of the penis acted as a semen displacement device.

"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.

Gallup and his team, who reported their finding in the journal Evolution and Human Behaviour, said the depth of penetration was also important in expelling more semen.

Their findings were supported with surveys of students who were questioned about their sexual experiences.

"Sexual intercourse often involved deeper more vigorous penile thrusting following periods of separation or in response to allegations of female infidelity," they said.

I am doing the wrong damn research...where are these guys working again?

LMAO- That DOES add meaning to “PLOWING the furrow”:p






… and Fussy, there is good science and science that is not done well. Always use caution when it’s prefaced with the words “Human Behaviour”.;)

I wonder if they can apply what they've learned to tunnel drilling. Hmmm. Isn't science wonderful? :)

I went looking for info and found these definitions in case any one needs schoolin like me;)


The glans: The head of the penis is keenly sensitive, the male counterpart to a woman's clitoris.

The coronal ridge: The ridge where the glans curves in to meet the shaft is a band of erotic electricity, particularly at the spot known as...

The frenulum: Found at 12 o'clock on the underside of the shaft, this fingernail-size spot is the center of his universe.

The raphe: This midline seam on the underside of the penis is exquisitely sensitive -- a zipper of nerve endings.

The scrotal sac: Gentle touching, please. You'll know you're doing it right when the scrotum tightens and contracts as if it were dancing.

The seminal vesicles: On the sides of the scrotal sac, the vesicles feel like little twigs. You can feel them turn rigid under your fingertips.

The male G-spot: To find it, search the muscular band of flesh that runs from the base of the scrotum to the anus for a slight indentation about the size of a dime. Pressing this dimple indirectly stimulates the prostate gland, as well as the inner base of the penis itself.

Very interesting Fussy and Lil......but Lil, I know another way of getting to the male G-spot......but Fussy won't let me try it. :(

you made the mistake when you asked;)

Depending on the guy, I find some are more stimulated externally than internally (within the anus). Requires some field research to find what presses his buttons...

I am willing to start a study....

You'll have no problem finding participants.

Now lou darling you know that's not strictly true :p

Hey I'm willing to donate my body to science!!!! Where do I sign up???

Is this the line for the science experiments?

Lilith was right!If you have confidence in your abilities,& it's not
something,that would go against what they would do,Just do it!
If you ask,they might think about it! Irish
P.S.Of course,it helps,if you know your partners morals,with you!
