The key phrase here is that he is a hot girl now. Textbook opposite-sex attraction. Kinda like how you wouldn't call a straight man gay if he was into a post-op, fully passing trans woman just because she once looked male. A 100% heterosexual man never would have been into her prior to her transition because he would only be into the female form. Same with this situation
it literally is SUPER gay because he’s moaning the guy’s name and he keeps referring to him as if he was a guy and using the excuse that he’s a “girl” to fuck him. that’s the gayest shit ever. “it’s not gay if you have a vagina bro” is what this basically is lmao. it might not be physically gay since he’s in a woman’s body but spiritually it is bc who fucks a guy they know turned into a girl when there’s another woman there

This is gay. if your male classmates turn into girl you fucking him was first thought smh
