I messaged a provider via email and asked a couple of questions and she responds with answers and then ask if I am interested in BBS.....thoughts?  This kind of threw me for a loop.

By BBS are you saying "no cover"? If so, not sure if that is a good idea, if she is offering that kind of service on your first contact then she is probably offering that to all of her clients. Way to risky from my perspective!

Same thought....not touching that with a 10 foot poll.

I was thinking the same thing.  

and first contact is certainly NOT one of them.

Some relatively closed groups of swingers do engage in unprotected sex, but they claim to be more or less sexually exclusive within their group and everyone has to get tested at least twice a year.  I don't think that's often enough.  
Can't think of many other situations where I'd even consider the idea while hobbying, or with civvies that I'm not monogamous with, for that matter.  And I'm done with monogamy.

Me too my friend ...me too.
