19 year old virgin

Silver
Hey guys so I'm 19 and still a virgin this was not intentional. I have had one serous relationship and got extremely close to having sex to the point where I physically had to stop him because the pain was too much. 
I'm currently talking to this guy that I like and he's 7 years older than me, this makes me nervous telling him that I'm still a virgin as he's a bit older and he would be experience. Me on the other hand not so much. 
I am just wondering that if I was to say something would it turn him off me because right now he seems keen to hang out. 
I don't really care if I lose my virginity and I'm not in a relationship I just want to like the guy.
Any help?!
