I won't lie. I may have joined this group because this conversation is hella fascinating to me!
First! We should have a brief discussion on whether or not we're defaulting someone's sexual orientation and/or gender identity! Does this trap/reverse trap identify as their sex? If that answer is yes, then they are considered cisgendered. However, does being a trap/reverse trap count as selecting a different gender entirely? To assume that someone's gender identity has changed because of their aesthetic expression sounds suspiciously like invalidating someone's gender identity to me. tldr If your trap is identifying as male, and they like to fuck boys, they are hella gay. If your trap identifies as male, and they want to fuck girls, then they're hella straight.
With Reverse Traps, just reverse the roles. RTs wanna fuck boys, super straight. RTs wanna fuck girls, hella gay.
