Player or Dickhead?

Ok so I’m still a virgin so but this has to do with sex so yeah. This story starts July last year and I was 15. A guy from school saw a post I put up of me just in a dress and goes hey have we met? And I said yeah kinda, we were on the same footy team during sport yesterday. He’s like yeah haha but not properly right? And I said haha no you’re fine. Anyway, we talk a lot for the next week or two, and one day, I don’t remember how it happens but it gets dirty. We end up being half friends with benefits because all we did was get each other off by texting what we would do if we were there and what we like etc. ok well he would get off and I would get really horny cause I’ve never orgasmed (help) then we’d get tired and go to sleep. We’ve never talked to each other at school or ever. And we r not supposed to tell anyone. It stopped a while ago last year, but I can’t help playing it in my mind cause is he just a player who doesn’t care and is just messing around with the new girl or is he being a dickhead without realising it? I’m really attracted to him, but he’s hung up on this other chick, and considering he’s really brainy, he hasn’t considered me an option. We still talk sometimes, but not dirty anymore. Should I try and move on or see if I can get him? If you don’t have an answer that’s cool, but it would also help if someone knew why I’ve never orgasmed and how do I make it happen??
