Judged for not dating

So I turn 15 on January 30th and all my friend have had or have a boyfriend. A few guys have told me that they think I’m really cute. At school they is a group of guys known as ‘ the group’ and a few of the guys I am friend with but not close friends with. One of the guys was telling me that quite a lot of the guys in the group like me and would like to date me but don’t want to tell me. And I just wonder why they don’t say anything. And my friend always make fun of me because I’ve never had a boyfriend and always ask me when my last boyfriend was when they know I’ve never had a proper boyfriend. They was all when I was 10 and when I thought I was in love but I wasn’t. And we dated for like 2 days and I thought i was going to marry him And it puts me down because i would like a boyfriend but I’m just like really awkward and don’t really know how to or what to do.

Help me plZz
