I been jacking off on the toilet so much that every time I smell shit, my dick gets hard. While I was driving home from work, I cut a fart and started to chub up. Anyone else have Pavlovian triggers? Doesn't have to be about hard ons, I just figured I'd share mine to get the ball rolling. Watch baseball and crave a hot dog? Hear a certain song and want a doobie? Smell a certain cologne and yer cunt starts gettin gooey?
