I'm in the minority, here, but I think the reddit post and his lack of insight into his behavior is creepy, but not the actual shirt-sniffing. Take away the AGP he's spackled over his libido: if a hypothetical based-metalhead goes to a concert with a female friend he's not fucking, lends her his shirt and then keeps sniffing it when he gets home, then maybe he just wants to fuck his friend. Our hypothetical metal-head probably recognizes this and isn't going to panic and tell on himself to preddit, because he has some understanding of his male libido and how it motivates him (A LOT). This idiot is horny and doesn't recognize it. It makes him "dysphoric"? Please. He sniff it, gets aroused, and then feels guilty and confused about it, because only bad men objectify women by daring to want to fuck them and he doesn't want to be one of those bad men.
Jesus Crist, how many of these teen and early twenty ROGD boys are just horny and guilty about it? Because you can't have a male libido in progressive circles anymore, you're practically a rapist. But lesbians can be horny and sexually aggressive towards women, that's fine, that's empowered. Do they all start out as porn-sick AGPs, or do some of them just want to crush puss, and they think throwing on a dress is the only way to chase girls and not get called a predator?
