I don’t have any “worst” one, 'cause I think they’re all good – spine-tinglingly, loin-throbbingly, heart-palpitatingly, mind-mushingly good.
But my strongest compulsion, and one that’s probably shared with a majority of my normal, healthy fellow malekind, is purely and simply to get naked with attractive women in mountain streams, mud wallows, and fields of corn, under waterfalls, on seashores, and up in trees. You too?
out of the choices present (ex. “other”), i guess that would be the bus exhaust… my greatest addiction is being out there on 2 wheels and just… going… which as a side effect ends up in me huffing the exhaust of way too many busses, blue trucks and 2-smoke scooters…
Nothing about autoerotic asphyxiation…? Or self-surgery…?
Actually my worst compulsion / addiction is plucking out the hairs of my eyebrows and beard, then “planting” the hairs in library books. (I hear they can keep on growing there for decades, nourished by the rich pulp.)
