legit thought you were gonna kill yourself thank god it's just nipples
if you still haven't found a solution, then moisturise the nips and surrounding area with a non irritating moisturiser (banana boat or something idk) then put a large cotton dressing over them and then tape over that. don't...
don't you get 35 minimum marksmanship as a cop as well?
anyway, if you're not very good at shooting, just play as a criminal more and try to get into more shootouts with the police when you can. it trains your skill and helps you understand both sides.
I shot officer Kyle Dinkheller with my rifle in 1998 for stopping me over a tail light. good times.
I was also detained and searched for showing someone my poppers because the twat thought they were illegal (he took them btw)
