I immerse my head and ears in hot bath-tub. When I get out I put my little finger into the wet ear and then fast pull it out which creates some suction in the ear which sucks the water out and I think also some vax.
I can't find it now but I read a story, in I think in https://old.reddit.com/r/tifu, about a man and woman having sexy fun times. The woman's thighs were wrapped around the guy's head, she orgasmed, her legs spamsed, and because of the sweat her thighs formed a vacuum seal on both his ears and ruptured one or both of them.
