Girls, I met a guy and got weak in the knees and let him do things I wouldn't normally let a guy do. How do I recover from this?

I had a hard week at work and I went out to have a few drinks with my friends to ease my head. By the time I had a few I got to talking with this guy who is tall, strong and HOT. He also had light brown eyes that are hard to resist. He took me behind the building and kissed me, and then he pushed my shirt up and kissed my belly and I didn't resist. We chatted for a bit but I'm not sure I trust him or myself, because the first night I ended up with my shirt up and that isn't me.
