it’s long but please help me

Okey so i’ve been dating this guy for like three months and the 9th he asked me to be his gf and i said yes, ‘cause well, i like him a lot. But i had this big secret, and it felt bad not to tell him so i did but now im so scared that he’ll run away. The secret was the following one: when i was 15 i was dating this guy that didn’t appreciate me and who made me feel like i was not worth of his time, or of anyone’s. One day we had this big fight and i was going out with my friends that night. In this group of friends, there was this boy that loved me since we were 12 and had asked me out repeatedly, but was in my friendzone. In that moment, he had an year-and-a-half relationship with this girl, his gf. But she wasn’t coming and i was there all bitchy so he made a move on me and finally got out of friendzone. We kissed nearly all night and i lost my v-card with him a week later, while he was still in a fight (but not over) with his gf. That happened in summer, a year ago, and i spent such a bad time. It was crying and alcohol and more crying and throwing up all summer long. When school started again I promised myself to never be in a situation like that again. I kept my promise ever since, and started dating guys who were actually worth fighting for. My bf is one of them. He’s really cute and sweet and treats me so well and makes me feel so loved but he’s so damn virgin. It kinda bothers me, but we’re teenagers, we’re 16 and it’s okey to be a virgin and stuff. And now he knows what i did and although he told me repeatedly that my past didn’t and will never change what he thinks of me, and how he feels about me, im scared to have scared him away. Please help me, tell me what you think about it, did i did the right thing by telling him? i didn’t want him finding out by another source.

And what do you think about the sex part? i mean i dont want at any cost to pressure him but hello a girl has needs. And i dont really believe that he’ll reject me if i make a move on him, but i dont wanna seem desperate either. any advice?
