What happens if a girl accidentally sleeps with the Anti-Christ?

I'm not sure, but I think that I may have done this Friday night. He looked totally hot and was totally awesome but then when morning came, he looked like hell. And talk about bad breath! What was I thinking? Then he showed me a tat of 666 on his hiney. I kicked him out, shook my Bible at him and told him to "get thee away from me in the name of Jesus". He seemed really scared by that and left. I think I just encounted the Anti-Christ. Now how do I get back right with God after that experience? Am I tainted for life?
