I don't have a boyfriend should I be worried?

Hey guys!

So the thing is I'm 16 years old and I don't have a boyfriend I see all my friends happy with their relationship and I'm not unhappy for being alone I only feel apart in some conversations.

I'm not that good with guys bc I'm afraid if I give myself to someone I'll end up hurt.

Can u please help me with that and give me some advices for not being nervous around guys bc I'm afraid that people don't understand who I am.
