Is this a serious question?
No, it fucking isn't. These idiots saying this shit don't know what "preferences" are, not to mention it's rapey as hell. They're basically saying a straight man (meaning 100% attracted to women and women parts only) better learn to love taking a dick in his ass (or mouth) or he'll forever be branded as a bigot, and yes, us men get this shit a lot, too.
Fuck these clowns.
