That is, Jordan didn't really write very sexy, but you could tell that it wasn't a neutered world. Pillow friends, the customs of the Sea Folk, Else Grinwell, some small asides about Green Ajah Aes Sedai, etc. The running gag of noblewomen hitting on Rand (I'm still mad at him for not getting with Berelain when he had the chance).
I might be reading too much into it, but it's more like Jordan was comfortable with sex, but just chooses not to focus on it, whereas Sanderson is uncomfortable, and actively doesn't mention it.
