Despite common opinion, science fiction doesn't have to be nerdy - it can actually be quite sexy. In fact, erotic science fiction is a niche market.
Usually, science fiction gets filled with commentary about our current world, with humanity living in a futuristic universe or alternate history. The authors typically point out the flaws of our society through the lens of a different space-time existence.

Erotic sci-fi isn't just for the perverted nerd. It's for any reader who wants to read a sometimes political piece that includes sci-fi elements and some kink.
