I have a formal in Florida and I asked this chick to go with me who I just met two weeks ago. It pretty much involves getting really hammered at the beach pretty much. I have a feeling we're going to have to share a bed and I'm not sure she knows or is aware of it. Should I tell her or just play dumb about it? The closest sex I've gotten with her was grinding on her for 2 hours, but she's a virgin.
