Women's sexuality, as is men's sexuality, is rooted in their genetics. Often the mistake is made that our genetics is fairly recent. It is not. We have been homo sapiens for about 200000 years. Sex is designed first and foremost for procreation. And to use a kind of analogy, lets *follow the money* or in the case of biology, *follow the energy.* And energy is really food, and protein is the rarest of foods.
Women have about 400-500 viable eggs, men have millions upon millions of sperm. Imagine the amount of energy used to kick out one egg during a woman's cycle. The uterus gets ready for egg implantation, there is growth of the uterine lining, and then if there isn't any fertilized egg the lining is shed and blood is lost. A ton of energy just to get one egg cycled.
If there is a successful fertilization, then imagine the huge amount of energy a woman has to devote to just carrying the fetus. Another huge energy expenditure. 9 months and upwards of 30-50 pounds of protein is dedicated to one thing, making a healthy fetus. The Placenta, another huge investment of energy is shed, and the new mother now starts lactating, another huge expenditure of energy.
And as I have said b/4 here, is there anything so helpless as a post partum female and a tiny newborn? Talk about easy pickings for a saber tooth tiger or a giant eagle or pack of dire wolves. That was the crucible, the real environment where our underlying genetics was formed. So a woman might be excited by a sexual image but at her core she needs to think of it way more than a man because it means so much more to her, based strictly on survival.
Now in that context, is it any wonder that women generally have to have at least a fleeting emotional connection with a sex partner? Is it any wonder that a woman usually will think about her sex partner far more than a male would? Is it any wonder that women might be at heart *whores*, as was posted here b/4? Whores because their very survival was dependent on getting lots of food and protection in order to have babies? A woman who just fucked anyone, without some regard to her well being if she got pregnant likely had her genes wiped from the earth in her death and the death of her baby. Thats why women are far more attracted to intelligence and men of *means* than they are a big dick.
BTW I am willing to bet that the humans larger penis is really an adaptation evolving as a sign stimulus for other men, not women. A male standing upright would display automatically his penis and I bet that in some way determined his pecking order. Think about it. Men are FAR more interested in penis size than women. Women virtually dont care. I am always amused here that SO many times men try to corner women into saying that penis size is a strong determinant for female to male attraction and just as many times the women here say *no its not.* It is way down the list of traits women look for and I outlined above my theory as to why. INnfact to go out on a limb, I would venture that a woman who bases her attraction to a male solely or strongly on penis size is in some way emotionally crippled. I guess there could be purely physical reasons but me thinks that is a very small percentage.
My gut tells me womens vaginas adapted to the increasingly larger penis and not the reverse. Hell a male mountain gorilla of 500 lbs and immense strength has a very small unit. He gets his females pregnant rather easily. A large penis is another waste of protein unless it imparted some genetic advantage, but the advantage was over other males, not female attraction. Women did not pick their partners until very recently. They got fucked by the more dominant males and even the weaker males. A female who could not accomadate a larger cock was selected against. I have been with a woman with a very shallow vagina and she could not handle the last inch or 2 of me. Not that much fun, and in the time b/4 antibiotics an abraded torn vagina could have meant death.
Think about it. Any woman who got a urinary tract infection, a rather common malady handled by gantracin today, probably died if she got it 18000 years ago. Maybe the first time she had sex. Her genes wiped from the earth. Its called honeymoon cystitis for a reason. Its been suggested that vaginas can handle any size penis but I know for a fact that isnt true.
