Should I let my boyfriend have a private couch dance with a stripper?

I have a boyfriend for several years. We have a very good relationship. I’m not a very conservative person, we went together several times to a strip-club, and even to a live sex-show in Amsterdam. I feel pretty comfortable with it (we pay, we watch, have fun and go home). We don’t do it weekly (once, twice a year maybe).

Recently we went to another such club, and he asked me if I’d mind if he had a private coach dance with a stripper. I didn’t really know what to say… On one hand, I trust him 100%, and I’m absolutely not concerned about him “cheating” on me with a stripper or something, on the other hand, when I am trying to imagine what’s going to happen there it feels kind of weird. Yes, I know, “she doesn’t want him, but his money, he doesn’t want her but the “product” that she sells”... but still, isn’t he supposed to touch only me, and only me him? aren’t these “sweet” memories going to pop up in his mind once in a while when we in a bed?

On the “third” hand, I don’t want to be selfish, and to prevent him from doing fun things, overall he is a very good guy that deserves having some fun (its not that he is going to have an affair with this stripper).

I have no problem talking to him about this, we have a very open relationship, but I know if I’ll tell him that I’m kind of disturbed, he won’t ever do it, and then I will have a bad feeling that I’m not letting him to have some fun. I want to be fun, and I want him to know that I am fun.

What do you think?
