Most Helpful Guy
Dudet, you are going fine. I'm 19 and in the same boat you are. There are a lot of people on GAG in general who are in the same boat you are, and as far as I know, a lot of them are actually pretty cool people. 18 is still young, you still have many years to get a boyfriend and stuff!
The worst thing you can do is try and force a relationship to happen that will clearly not work, just for the sake of getting a boyfriend or first kiss. That will only leave you with problems afterward. I'm not saying to not pursue a relationship with anyone, I'm saying that you should choose who to have a relationship with. Don't feel pressure to have a relationship, despite what your friends are like. Everyone goes through life at different pace. I know some people that married their first girlfriend and are currently living happily.
Tl;Dr; Don't worry about it! :D
