Heh, I went on my first date when I was 14, with a 17 year old guy who ended up being my boyfriend for a couple of months (I was a sophomore, he was a junior)... two of my uber-conservative friends were appointed chaperones, and they came with us in the car and sat behind us in the movie.
We didn't even kiss the whole time we dated, mostly because my mother was so paranoid and expecting him to be some serial killer (we were both church-going kids, which made it even funnier) that it totally freaked him out most of the time. She caught him hugging me tightly at a roller-skating rink event and that was the end of it.
So yeah, just don't be like that.
Sounds like you are doing all the right things, anyway. My dad used to introduce himself to my boyfriends while holding a baseball bat that we made, which was more of a joke... but still freaked some of them out.
