Firsts

Hi all!  So I'm 16 years old and I just got a boyfriend. For the first time. I've never been kissed or done anything and he knows that. One day, we were on a date and I knew he was going to try and kiss me and I freaked out (mentally ha. He didn't know), and I prevented it. We are going out on Saturday and I know it's going to happen but I'm so nervous and what if I'm bad at it and I don't know what to do!
