The label or term gay, in my opinion, is when you prefer men to women. Also in the heat of group sex any sexual organ is game. Personally I loved the position of being under my partner in a 69 while she was being fucked from behind. This put me within CMs of the guy or guys cocks and balls. I have taken a cock in my mouth just after he has cum in my partners pussy or sucked a ball as he is about to cum making the guy explode into her, but never ever have I thought about kissing a guy after. That thought makes me feel like puking and REALLY turns me off.
So no you are not gay to suck a cock or two (no not a cockatoo) you are simply bi like many cucks are ,if they truly admit it and also the bull usually gets off on the cuck sucking them afterwards aswell
