The way that Ann phrased the STD question was good if you decide to go the route of suggesting she gets checked out. But are you at the point in the relationship where that should come up?
If it were me, I wouldn't allow myself to have sex with her yet, but that's me (Or maybe I'm high. Maybe if faced with sex I wouldn't be able to help myself). I think that it's something she should take the lead on in a moment of sobriety and when she has those feelings for you again. I wonder if you would get more mileage from holding off on sex until she's got the warm and fuzzy feelings for you again, rather than allowing booze and the moment to dictate things. Just a thought. I've always been old fashioned that way though.
