Point is, everything goes on. Maybe there is some etiquette, but it’s really about finding what you want and doing it…or letting it be done to you. You can watch, you can watch with your cock in your hand, you can fuck or be fucked, or be fucked with another cock in your mouth, or you can go in and have a look or a feel and if you don’t like it you can leave. No shame, no worry about being judged. Everyone is nervous at first (mostly), and if you can learn not to worry about it you’ll have a great time, and maybe discover something you’d never dreamt could happen.
