@yababylol:
I had a conversation with a friend of mine about this recently, about how when we were both in our teens (this was before there were hookup apps), we'd read about these places on the Internet and try to naively go into the parks and bathrooms that were supposed to be "active" and see what was going on. We were horny and sooooo curious!
He never saw anything, but I once actually had a trucker's dick shoved at me from under a stall in a rest stop near my work when I was 18. It was the first cock I ever tasted, and I never saw the guy's face. I was happy to finally experience giving fellatio, though. Someone came in and I fled in terror. I never tried again; I was young and worried about the awkwardness of encountering a "troll" (a mean name for someone I wouldn't be attracted to, everyone used it).
Nowadays, I think the practice is all but obsolete because of Grindr and all of its clones, to be honest. You can cruise and see pictures, and the only question once you both realize you're game is whose place it happens at.
Well said..
