I've posted about this before, but only once and it bears repeating. Many of us enjoy going to the gym or a day spa to enjoy some time in a sauna or steam room.
My personal favorite is steam. Most places add a touch of Eucalyptus which aids in clearing out the sinus.
The other thing a lot of men enjoy about this is the opportunity to relax completely naked. Soaking up the heat. And, I suspect that this goes on a lot more than most places want to admit. Many a straight guy will happily accept a skilled hand job. Some actually go specifically to seek it out. (It's okay, straight guys. Really, we won't tell if you won't.)
But, I caution you all - not about the worrisome issue of being discovered with a hand or mouth wrapped around your boner.
But picking up a staph infection due to sitting on the benches without a towel under your ass.
Staph loves a warm, moist environment, it thrives in the groin area. All it takes is a small pimple you aren't aware of, or a scratch or nick from shaving the nutsack, and the infection has found a way in. And, some strains of staph can be extremely voracious. A few years ago, a young man was hospitalized with a virulent form of staph and died within three weeks - he'd gone into the steam room or sauna of his local gym without a towel under his butt.
In fact, don't sit on any surface at your local gym without a towel or briefs between you and whatever you're sitting on.
Always have something to protect you. I don't care how clean the place looks.
Better to err on the side of caution. And, even though it's Masturbation Month, unless you are in a gay bathhouse where things like jacking off are accepted and happen out in the open,
don't get caught with a dude's hand
or lips wrapped around your cock.
