For me they need to keep their feminine appearance, even if they have a lovely cock dangling between their legs. If they have tits they can go naked, if they don't, they need to keep their top on. Stupid I know, but if the female apparition is distroyed (seeing they have no tits) then I think I'm fucking a boy (yes, I know I AM fucking a boy) and that makes me gay
. If he's got tits, or keeps his top on, even when I'm taking the full length of his cock down my throat and massaging his balls, then I don't feel gay.
