Nice write up and man, those nasty rashes are tough. I've not had that problem but I can see how easily it would happen. I generally wear some mountain bike style cycling shorts and at the end of each day, I try to change out of them, rinse/wash them a tad if possible, and then hang them up until the next day. I don't know if this really helps at all, hahaha but I've been paranoid about it enough to always do it :D
