Just curious

So I didn't know what to put this under so I put it in this. I'm 12 turning 13 in January sound young, that's the problem. I'm supposedly not meant to have a boyfriend till I'm older but I've have a few. Been on a 'date' with one of them at the movies but my mum thought I was going with his sister. This time I wanna go with another boy to the movies,idk when. How do I do it without being rejected by my mum? 😂
