I have it on pretty good authority that everyone who likes having sex with humans likes female boobs. And plump round asses. It's some deeply ingrained evolutionary stuff.
Doesn't mean a gay guy is gonna go straight because of some nice tits, but he can appreciate them erotically.
even straight women like them. I was listening to some NPR thing about this guy in his 50s who got implants, and sometimes wears dresses and heels, but still considers himself a cis man, and his wife said fucking a man with tits is one of the hottest things you can do.
