In my humble opinion there needs to be a penis for it to be gay, and pooners are biological women with vaginas, therefore I believe that engaging in inappropriate relations with a pooner is not gay.
It gets faggier the more pooned out she is. There's a difference between a girl that got groomed by der cord and hasn't even taken T, and one of those keptsecret pooners that look like hairy twinks with the wrong genitalia.
