How do I avoid such conversation withy crush?

I have a crush on this guy friend we talk for hours... but the thing is he talks even about his visit to strip club and the girls he saw there... it's kind of getting on my nerves... I now feel that he doesn't have any feelings for me and that's y he speaks about those things... but I can't avoid him as he is my friend but how can I avoid such conversations
