I noticed people saying that it wouldn't be natural for a boy to expose his chest in public areas like restaurants or classrooms. But surely, as long as you're just doing it once or twice, you can just pretend that you're feeling some discomfort or irritation to play it off. I feel like even a girl could get away with that with some proper setup and staging.
Fact of the matter is that under normal circumstances, boys are not embarrassed about exposing their chest. He's actually getting mentally programmed to behave this way. Super fucked up. Love it.
