Smut is not allowed on RPG, irrelevant of what individual RPers think. No matter the age of characters or RP setting, smut is never allowed in a public RP, based on the overlaying rules of Roleplayer Guild.

I ticked the 18+ box because of darker themes, blood, gore, drugs, violence, whatever. Everything except smut. 

If you see an RP on here which includes smut, it's breaking RPG's rules, so you don't need to think that 18+ involves smut on a general basis. It never does.

I removed the category in either event, since you were confused by it.
