I don’t touch the snaps because when I tried on the first innerwear that I bought, the snap broke so it only seems to be a plastic rivet. I don’t need tighter band, anyway. I do pay attention to make sure that the smooth side is against my skin. Also, I was bothered by testicles sticking to my leg, but I solved this problem by wearing a no-show sock over the innerwear and scrotum. Sometimes the sock wants to roll off of my scrotum, so I bought “underwear bracelet” from Amazon to retain the sock.
I found that it is necessary to remove the Stealth before urinating. If I must use a public restroom, I go to a toilet stall for privacy. I can usually lay the stealth on the toilet paper dispenser, or put it in my pocket until ready to reinstall. I also always dab the end of my penis with toilet paper to get the last drop, just in case.
