So, I'm rereading one of these, which is why it sprang to mind, and I don't know if you're fannish about any of this author's fandoms, but Vathara on FF.net is an author who I really enjoy for the sheer worldbuilding of just about everything Vathara writes, but particularly the crossovers. Vathara does a lot of crossovers, and while some of the fic have romance, there's very little to none that I can think of explicit porn anywhere. (Thus, no bj.)
