Shall I tell him ?

I'm a little afraid. I'm 23 and never slept with anyone. For me it's not that much of a big deal. It just never happened. I had relationships before, one quite long but there he wanted to wait until marriage and that was fine with me and as that broke off i dated a bit but i just never felt comfortable with anyone or even actually had feelings for someone to be honest, It takes a while for me and everyone was always super fast so i always decided against it and walked away. I'm okay with it. But it seems like around me it isn't very normal so I never even told my friends about it. I just made up stories or just took myself away from those conversations, just listening. Now there is this guy that I really like. I've been liking him for quite a while now, 3 years maybe ?. Apparently when I catch feelings i cannot really let go. Anyway it's been quite something the past year, but nothing really more than cuddling. I used to wonder what that is in between us and it kind of drove me crazy inside but we recently kind of talked about it and well he's just into sex for now as he doesn't want a relationship. For me it's fine. I mean we're kind of friends, talk a lot and it's just super easy to be around him, he makes me feek comfortable and he is super genuine and kind. He recently asked me if i ever considered sleeping with him and i really want to but i'm a virgin. And he is 30. I don't want him to scare off. As if it's a responsibility or something. It's not a big deal for me but i feel like the lack of experience on my side might be unattractive to him. We meet again next time and i'm really unsure whether to tell him or not. But if I don't he might notice it anyway or might think i'm bad and that would make me feel weird i think. But i'm not sure if it might scare him away and he might think i'm weird. and we do work in the same company but different departments and then it might turn weird there. Does anyone have experience with a similar situation? Is it something to worry about ? So the issue is just really whether to tell him or not. I'm sure about anything else..
