If you’re under 18 and post lewd things don’t be upset when adults get mad or call you out. People go to jail for having that shit in their caches or on their servers, plus a lot of adults just find it gross.

Wait to be lewd like the rest of us.

Oh and if you’re under 18 be upfront about it please? It’s a safety and liability concern for adults.

Like if you get upset because adults won’t flirt with you because you’re under 18 or you’re afraid they will then consider that they have very good reasons for that! They don’t want to go to jail! They don’t want to inadvertently do something they find repulsive. It’s really that simple.
@Elizafox +1, knew a guy who iirc got a visit from the cops because one of his underage coworkers was flirting with (more like at) him. beyond being actually illegal (and not in the "victimless crime" [read: based] sense, the "actual crime" sense) it's also just cringe.
