I might have talked about this before here, not really sure, but what I play a lot are several hentai RPGs. I kinda got hooked on one a few years ago called Harem Collector. The main character's quest is to collect 151 slave girls (it's a magical number, don't you know?)
So yeah, there's a lot of BSDM sex and that kinda thing, which is right up my alley, but believe it or not, it's actually a pretty good game. The storyline is strong, the gameplay is good, there's a good smart-ass sense of humor and odd pop-culture references throughout. The main character is described as "chaotic neutral" a few times, but I think he's really a little bit on the good side of that, or at least I like to imagine he is. (the game's not completed yet, so the storyline ain't done)
