sex ed and lgbtq are completely different every parent has "the talk" with their child at the age they feel appropriate, i didnt have sex ed in school and my di'ck works just fine and you're a 'fucking ass'hole if you think its not wrong for men to change with women.
Also i dont think ppl should be changing with other ppl in the room thats weird asf also with the way t is going down in a few year the biolocal difference won't rlly be a thing like across the board
