For the ladies who don't make their man use condoms, there is an nasty smell to their semen too. You can clean on the outside, but there is that bad nasty smell still there that will linger. Nobody talks about it, but things stink - semen, periods, and sweat. That thing is nasty. I could never be gay.
That thing can just stink on it's own with nothing wrong with it. Use just water. Yeah right. The body stinks - butts, crotches, armpits, breath, hair, feet, belly buttons, etc. If you don't clean it, it will stink.
I like the blow dryer idea. That sounds very sanitary. You use blowers for hands in the restrooms. Why not on the crotch area. That's a good idea.
