Being physically attracted to women (and only women) is kind of the entire definition of a straight guy. Nothing else really counts.
Women are extremely lucky they have all those amazing lady parts, because if they didn't we would never put up with them. Women have what men want, not the other way around.
True, there are never any strong feminists around when a) a refrigerator needs to be moved up a flight of stairs, b) a spider needs to be killed or c) a jar just won't open. But don't fool yourself into thinking they need us for anything more than that. Except for a few sperm donors and auto mechanics, women would barely notice if men went extinct forever.
If I didn't have such a high sex drive, of course I'd be gay. It would be easier. No violent mood swings, no games of Guess Why I'm Upset, no waiting for an hour while my lover picks out shoes, I'd have space that is actually mine in the bathroom... it would be great. But because there is always a catch, there's a catch.
In this case, the catch is... no vagina. Ever. And nope, that price is just too high.
