I think I'm pretty comfortable sharing my reading habits but it's not something I volunteer, much like being in fandom to people in RL. I will say that I almost always read NC-17 and it's partly for the sex but the intimacy is definitely one of the most important parts, that feeling of deep connection you often find there and I'm more able to get an emotional response. I like finding stuff I wouldn't see in the source text and sex between guys usually isn't one of them. I'd be a bit more hesitant sharing any kink fic I like but then again it's fandom which is generally pretty accepting of most things. I'm fine with leaving comments to anything because I assume that either no ones reading besides the author or that readers have already read the story and don't mind it. In the end, who cares what you read, fandom's there for you to explore everything there is.
