Sex on 4th date??

Guys, let's say you've been on four dates with this girl you've been talking to for a month. Now, on the fourth date, you decide to bring her over your house to watch a movie. Then, you start kissing her on the lips and she pulls away saying "That's it." And your shocked, so you say "Are you serious? Why?" and she responds "Because kissing leads to other things.." and you say "What, you can't control yourself?"

So this all happens on the fourth date. Who do you think is wrong?

(Girls can answer this too...)
