I'm a 19 year old girl, and have a similar situation as you, except with guys. I actually had a boyfriend my freshman year of high school, but we broke up because I was afraid to even kiss him. Haven't had a relationship since then. I'm just waiting for the right guy to come along and understand my inhibitions about being in some sort romantic relationship and is patient about them. So my advice is similar to those above, there is plenty of time to get into stuff like this. I know that the pressure to be in a relationship in high school is high (it was for me anyway), but, also like those above have said, don't worry too much about it.
