can girls orgasm through fingering? is something wrong with me?

So I'm 17 and I'm dating my 17 yr old boyfriend and we are sexual- I'm a virgin. He has only fingered me once ( it didn't hurt like everyone said it would..?) but it felt really weird. I didn't orgasm and when he rubs me I don't orgssm either and I feel like he gets disappointed i don't. But also I'm to scared to masterbated bc one time when i was younger I got a cold sore on my mouth and my mom said it was from putting my hands in my pants (I was like 10) so I never did it again. I make him cum and everyone says how it feels amazing to cum, and I just can't. Is there something wrong wit me? (Also please don't judge).
