Oh gawd waiting I read your last line 5 minutes ago and am still laughing. The imagery!!!
Unfortunately I have seen the "picking balls syndrome" What I have noticed is that they are constantly trying to readjust positions or underwear. Perhaps they are too tight or too loose but the discomfort tends to send men to the area to picking the offending garment away from the area.
Despite the fact that I don't have any of the said balls I do have (and have lived in the same house with) 3 brothers, 3 uncles, 1 father, 1 step-father, 6 boarders, 1 husband, 1 live-in boyfriend, and 1 foster father (who was a gentleman in front of mixed company and the only one I never saw him pick his balls), and now a second husband (and Yes I have seen him do it.)
Maybe men need to be fitted for their underwear like we get fitted for some of ours.
