Well, the same applies to Rothfuss about sex. In NOTW, there is hardly anything, but in the second one, there's a certain scene where it gets much worse and then there's much more for the rest of the book. Still not too bad, but way more than the first.
Rothfuss has more, I'd say. It gets slightly graphic, but Voidus or Edge could probably explain better. Weeks is actually probably about on par with this RP. There are some nude people in a few scenes and some thoughts about sex, but nothing graphic.
