Hello,
I am in the SF bay area this weekend and travel here quite frequently. Looking forward to be tied up and used.
I'm not sure about the current rules on single males, couples, etc...but try to go to the Power Exchange. You might be able to be abused and used up for free. If things get out of control, the police station is right around the corner too. Report back.
Is the Power Exchange still open? It used to be a multi-floor bar with different "themes" on different floors. It wasn't for me, never wanted to be a part of sex spectator sport as the man in the arena.
I'd suggest that he go to Diva's and hang out there. If you can't find someone that you like at Diva's you are a guy that is pretty hard to please. There used to be a bartender at Diva's, Asian girl, that was always really helpful in steering a person toward what they were looking for that night.
Yep it is still there but it moved deeper into the tenderloin by the police station. I agree about the Asian bartender on the second floor and Divas too.
I don't remember that bartenders name but she never steered me wrong. She would say stay away from those two girls or this girl is great, go talk to her. She told me once she was married, that dude was really lucky, he had a great wife. I owe her a couple of nice bottles of wine for her sage advice.
