If men like women with big boobs, do gay men like men with big man boobs?

Oh Iz, leave it to you to ask the tough questions.

I know some gay men that find larger men more attractive. I believe they call larger, gay men, bears.

Anyways... I think the reason why straight men find big boobs so appealing is because it's encoded in a straight male's DNA to find a fertile woman. Big boobs mean better equipped for feeding children, but I'm sure that's not what straight men think when they see women with big boobs. The attraction to big boobs is more like an instinctual kind of reaction. So, I believe there would be no logical reason for gay men to like man boobs because the man boobs serve no purpose (in regards to fertility).
