Heya! First of all, if I understood correctly you feel different from other teenagers because you haven't kissed someone in three months. Honestly from what I've observed, it's totally normal to not be dating or anything. I haven't kissed anyone for SIX months, and I consider myself to be perfectly normal.
I don't really know how to console you, because I would probably feel nervous in your place too; the ony thing I can really contribute is that in my opinion, nervousness comes from a lack of self-confidence, like there's this idea that you might mess up and look like an idiot. It always helps me to put myself in the other person's shoes... if my date was nervous and wasn't talking much, or if they knocked over something from stress, or whatever other awkward thing they might do, that wouldn't shift my opinion of them. Everyone messes up, everyone can be awkward, everyone is at least a little self-conscious, and you are no less amazing for being awkward or self-conscious.
I hope it goes well, take care pal xxx
