Yeah its that simple. Put the money in the slot. Video starts up and a timer that doesn't make much sense starts ticking down. The larger the bill the more you get for your money. A time bonus if you will. Now I wouldn't put all my money in at once. Sometimes you get people who are rude and will sit in the booth next to you and not be what you are into/ sketchy/ stinky dick/ etc. Put in a few bucks or a five and see how it goes. Sometimes no one comes into the next booth because they didn't see who went in. Anyways always happy to chat/help. Hope you have some fun. When are you planning to go?
Hmmm I don't really know. I've run into some in my adventures. A la craigslist, glory holes and just random hook ups. Have you tried Cock bar? I've heard things get raunchy there, but I haven't tried it. Grindr is also a way you might try.
They typically ask for money first. I just refuse. I don't pay for sex. I haven't had anyone try and intimadte me. They may refuse to leave the booth so that you can actually find what you want. There is also staff there, so it isn't like you are that alone, ever. I still manage to find what I want there most of the time.
