At least according to the story I heard, it happened like this:

On the last day of creation god looked into his toolbox and realized that he had two abillities left that he hadn't distributed.  Since Adam and Eve were his  favorite creations he decided to give them a bonus.

So god came to them and said "Okay I've got two more gifts left in my box, and since you guys are my only intelligent creature I'm gonna let you pick who gets what"

"okay the first thing I've got here is 'The Ability to Pee Standing Up'"

Well, Adam got awfully excited about that one and he jumped up and said "oh! oh! give that one!  that would be so great! Being able to go pee anywhere I want without even having to slow down!  I mean I could write my name in the snow,  not have to leave the Shower to take a leak, yeah that'd be awesome! oh me! give it to me"

and Eve said "well if he wants it so badly, go ahead and give it to him, I 'll just take whatever's left"

And God said:  "okay Adam, you can now Pee standing up" an Lo, Adam grew a penis

Goid then looked at Eve and said "well the only other thing I've got left is "the Ability to Have Multiple Orgasms'....

The blood vessels for the retina that run in front of the retina instead of behind, thus rendering a small part of the retina "blind".  Squid eyes have it right.  So how come the creator did a better job on squid eyes than people?

I've often thought that me and my lower back have more than a few arguments against the intelligence of this design...

Maybe God just forgot to carry a two or something somewhere, which I could understand, as I'm perpetually losing a sign or some stupid shit (the area is... lessee, negative 26!). But then I guess there goes that whole infallibility thing, POOF.

And us females had to get something exceptional out of that whole "you'll be in excruciating pain once a month" deal. But maybe that's just my opinion.

...that the fact women, on the average, take a good deal longer to reach orgasm than men has an evolutionary significance. It's supposedly a way to encourage women to find men who are considerate enough to pay attention to their partners' pleasure as well as their own. If a man is thoughtful enough to hold off until his partner comes, the reasoning goes, it's more likely he'll be thoughtful enough to do other altrustic things, such as support his family properly. Whereas the fire and forget crowd....

that the Creator (or nature, or whatever force you choose) understood a great deal about the repective nature of both males and females....it was necessary for certain limitations to be placed upon the male lest he literally screw himself to death.

Considering it wasn't until the 70's that the myth of the vaginal orgasm was revealed and that our society is entirely centered around the phallus and men's ejaculation, I don't think it is fair to say women have a better deal.  

Most men still think women get off from vaginal intercourse, that's a design flaw in men.  You're also conflating sex and gender.  It's men/women males/females, not men/females.  One is biological, the other is social.

Women are just better at faking it than men.
