It should just be G. Lesbians and troons are trolling. Every lesbian I know has had cock before and nearly every troon I've had the displeasure of meeting are sexually attracted to women. Explain to me how you dress as a woman, feel you are a woman, and want other people to see and treat you as a woman even though you want to put your penis in a woman, it's insane.
Piping a woman is the straightest, one of the manliest, men exclusive activity you can engage in. I have my grievances with gays but they're gay thick and thin and serious about it.
