Is it normal that when i masturbate, i don't feel anything?

Okay, so, I'm a young female girl and about 2 years ago, I had a girlfriend and she eventually talked me into having sex with her. The point is, when I would finger and rub her, she'd cum. When she fingered me, at first, I felt an excruciating pain. Then after a few weeks it died down to either feeling nothing or a little bit of pain. And when she'd rub my clit I didn't feel anything, same when she ate me out. Now, 2 years later, I still feel nothing when my clit is being rubbed or when I rub my clit and nothing/pain when I'm fingered and when I finger myself. It's not that I don't like girls or that I'm not aroused, because I am and I do.
