Sexual Exploration Skepticism

Lately I have been reading Macho Sluts by Patrick Califia, and I don't know what to thing. I know I have a little bit of yearning for the s/m scene, but I don't know how much. I don't know how much I want to get into it because I would rather not have sex rule my life, and I would rather it not be a part of my physical identity. I don't want my sexual tastes to determine who my partner is. It's kind of exciting to try out new things with my boyfriend. But I can't help but feel like a pervert being interested in these kind of things.
