Sex, sex and more sex!

Have you seen the previews for the next episode?
Yeah.
Here's the general gist: Sex, sex and more sex!
The preview clip is below if you haven't seen it already.
So who's rolling in the proverbial hay?
Alex and Lexie... more sex. (What is WITH that...by the way? What happened to the love of his life, Rebecca? It's just a booty call, right? Even so...!)
Derek and Meredith... caught naked after sex by the person who may as WELL be her dad. The Chief.
Izzie and George... something weird during having sex. Maybe it's not going to be all peace, love and mushrooms, after all?
Oh.. it seems Dr. Mark Sloan - the original male slut - is going to develop a crush on someone. We're not telling who... but you can probably figure it out. It's always the ones who play hard-to-get, isn't it?
