If it wasn't set up as a potential play date, and I doubt that you would knowing both you and J-Go, then it is just a meeting between people that have common interests. I guess I am not of the camp that the only way for a man and woman to enjoy each other is in bed.

Treat the Dom with respect unless he proves he is unworthy of that respect but also treat him as a friend. I am sure that if he is a worthy friend and honorable Dom he will treat you as a friend that respects not just the woman or the sub but the friend.

I ramble and agree that J-Go should set any ground rules he feels is neccessary
