One personal thing that irritates is gents that have shaved their crown jewels and then have very stubbly balls because they failed to deal with the re-growth. Really scratches and tickles, not to mention can make you gag when you know what.... Sort of makes me think of thick pork belly meat pieces that have stubbles on the skin left, chefs tend to usually burn those coarse hairs off but this might not be a good idea... lol
