I don't think it was sexuality specifically, rather all the feelings that timid, mousy Jennifer Walters had been bottling up, but certainly sex would almost certainly be a part of that.
Not to say she didn't have limits; I remember a subplot where someone, without her permission, took pictures of her sunbathing topless or nude (can't remember which) and sold them to the media, and she was furious. (I don't know if anyone ever asked her if she'd be willing to pose nude.)
But for the most part she's been portrayed as having a very healthy sex life and enjoying flaunting her sensuality. Not that she can't change her mind, of course, but I imagine that being a change which would take a while, and to my knowledge that didn't happen.
