Great topic from a newbie! I have wondered how much of "size doesn't matter" is self-censorship. I think most of the things that we were told didn't matter did in fact matter. It matters how tall men are, how big their cocks are, how much money they make, how good-looking they are, if they have (great) hair. Many women like men "beating the shit out of another man", especially if the 'fight' is over the woman. I say 'fight' because usually, the aggressor is much more equipped and there is no match - I guess the same goes for countries. I do think that much of it is cultural.
And of course, the same is true of women. If a woman thinks her tits are small and shapeless, yep, if she thinks she's fat, men probably think so too. And let's face it, standards are tighter now. Even if a woman feels pretty good about herself, guys still might think she's a heifer. Sad but true.
And yeah, race. It matters. Anyone catch the 20/20 Stossel report on Freakonomics? White women are the holy grail for men considered as a group. Now it's true that men are more likely to be attracted to women of their race than men of other races. But consider that an Asian (meaning Oriental for all those outside the US) man has to earn, according to the theory, US$150,000 more than a white man to even the playing field in order to be attractive to a white woman. I don't really buy that there is something to it.
Should any of the above feel guilty for what they want? Should men feel guilty for prefering good looking women to fugly ones? Or should Orientals (and Black men) feel guilty for prefering white mates to "their own kind"? Should I feel guilty because genuine size queens (not posers) turn me on? Probably not. Most people don't get what they want. Most people have to settle for second or third best. Look at all the matches made in 7th-hand heaven. Ever visit a nightclub and see the show? Women who are clearly not very good looking acting all high and mighty. And guess what - many will get laid. Not all guys can get a 10, but they still need to get off. If this weren't so, we wouldn't breed. We wouldn't take jobs because we knew some high-esteem pert-titted less-qualified tart was getting double your pay for the same job. But that's just the brave new world honey. Deal with it sugar, and ride that daddy for all he's worth.
I say go big or go home.
