I found out my husband has a strange . What should I do?

I found a bunch of youtube videos about girls in their underwear farting. A lot of men think it's hot and stuff and even pay money for people to fart on their faces. He accidently left what he was watching on the computer. I know he's into it, cuz he left a comment on one of them saying how he loves the smell of a$$ perfume and he would marry the woman that did that to him and never cheat on her. Does that mean he cheats on me? I also snooped in his email and found numerous other things about women farting etc. I had no idea that he was into this. Should I start doing this for him? I don't mind farting on the guy, but I really thought he found it repulsive. I guess I should just talk to him about it, but how do we get over the embarement of it? Thanks in advance.
