Good God, not this again.
Well, first of all I have to say what I've said in other occasions: the male equivalent of the female chest (in the matter of "sexual attraction") is not the penis. It's... the chest. Or more like the musculature in general. A well-toned body (not something too overkill, like say, Kratos, or Marcus Fenix)(also, ass-cheeks are included here too) is as attractive to women (or at the very least gay men) as a decent pair of tits is to men.
Secondly, unless you are a fetishist, an oversized penis is not attractive. Period. And even then, I'm sure outside of porn everyone would find it pretty disgusting. Just think about this: would you find mons the size of steaks attractive?
