Not so much fetish as is just some turn ons. Androgyny is just so lip biting inducing mmm. Tomboys, Traps, feminine Males, Masculine Females (though for Masc Females I'm still too much of a Top/Dom to ever be submissive). Doing sexual things outside is just so fun/nice. Taking your partner from behind either them restrained or not doesn't matter there is just something animalistic and passionate about it no matter if it's done kink or not. And who can forget nice butts.... nice butts are just so mmmm drool hehe.
Edit: Small edit, though some girly girls are lip biting inducing though being Pan I don't really care about the gender so much as the personality that goes with the body type, it's the pairing of them that is intoxicating.
