Internet progressed to Strip Clubs...What's next? Should I wait around to see?

My boyfriend and I have been together since college, about 8 year, still not married but it seems to be in our plans. My only concern with him is that he is really into . I found out about it and was freaked out about how often he did it. I'm becoming ok with it since he doesn't communicate with anyone via phone, chats or IMs as far as I know. But it's not progressed into frequent visits to strip clubs, which I am not ok with, especially since he can't admit that he's going. Should I be concerned? I am b/c I feel that the physical aspect and contact is now there. What should I do? ignore it? I don't think that I can live with knowing he can't/won't share something that with me and blatantly lies about going. I'm almost to the point where I feel like showing up there just to prove my point.
