It's HBO, so the show doesn't have to be as prudish as its network counterparts. And we could have mined a lot of HBO/Showtime material for this list because there's a lot of the having of the sex on those shows—Entourage, House of Lies, Californication, all the way back to Mind of the Married Man and First & Ten. But there's a difference between having sex on a show and being truly sexual.

When Kenny and April get within ten yards of each other, something electric happens, and they just want to jump each other's bones. Even if April manages to give Kenny the Heisman, you know she didn't really want to. Star-crossed lovers? Maybe not—but sexual enablers, absolutely.
