I recently found myself very interested in doing those type of things. I really enjoy walking around stores with an erection in loose ball shorts with no underwear and getting woman to notice. I also love filming big tits and ass, getting great screenshots is so hot. How can I stop my game up and improve. I live in Michigan. I want chicks to want to watch masterbate publicly. Help!!! Lol
This is one area where being a woman has its benefits. I have found I can get away with public nudity and even public masturbation without getting into much trouble. At most a cop might tell me to cover up. I've never been arrested though a few times I thought it was coming to that. But a man that is different. I'm sure you would be arrested and charged with a sex crime. Be careful. Most people who see a naked man especially one touching himself will at least act shocked if not actually being shocked.
Wearing very loose shorts with no underwear allowing for lots of “accidental exposures” is most likely your best bet. Even then you can't be touching yourself. Even on some nude beaches a guy touching himself will get escorted off the beach where a woman doing so would only attract a group of onlookers.
Sorry I can't be of better help but sadly that is about the way it is. Good luck. Be careful.
