Is lack of experience a turn off?

I'm a senior in high school and I've never had a girlfriend. On top of this I have never kissed a girl either. I think I'm attractive and I do get a lot of looks in public. Just when it comes to talking to girls, I always choke-up and sound like a 12 year old. Is it bad to have never kissed a girl by the age of 18? I pretty sure I'm the only guy out of my friend group that has never kissed a girl. This also kills my confidence because I'm afraid lack of experience is a turn off?
