What age did you first date someone?

I’m 18 and I haven’t been in any serious relationships. I’ve had a couple things that never went anywhere besides flirting and messaging eachother, but that’s it. It’s something I’m really insecure over. My older sister (22) was picking on me the other day for “not getting my dick wet yet” and today my younger sister (12) was picking on me that my older sister had boyfriends at 15 and I’m an adult and never had a boyfriend. My friends will pick on me about it as well.

I don’t think I’m ugly or anything. It just hasn’t happened, I live in a small town so my options are limited anyways. It really bothers me though. I feel like it’s never going to happen, and like I’m such a loser.
