Question

Hey everyone, I am interested in heading in to suck my first cock. I like the idea of it being anonymous, but I have a couple of questions.
I have seen a lot of posts saying people just hang around in the hallway. Is there a specific day or time to go that this doesn’t happen? Or is it just luck of the draw? I live a few hours from perth and this is my first time doing anything like this. So I don’t really want to make the trip i’m going to turn around as soon as I get there.
Also do guys normally pull out if they see another guy in the booth? Or just personal preference I guess.
Thanks in advance
