Never had a boyfriend before

I talk to so many guys but I've never actually dated OR EVEN KISSED A GUY! I feel so behind. I'm 15 and I have had the opportunity to meet so many new guys who I have met on Facebook or Instagram but I turn down because I have social anxiety and that makes me scared of interaction and humans basically. Most of my friends have had boyfriends or their first kiss and I just feel like I can't get a boyfriend because I'm ugly. I'm also really selfconscious and I hate how I look and what I my body shape looks like and I that is a big reason why I can't bring myself to meeting new people. I just want some experience because I feel so behind on teenage and boy life 😭 I feel like I am the only one, is there anyone else out there
