Can’t get turned on

I just turned 16 and I’ve had a handful of relationships in the past where I let them finger and eat me out but I’ve never gone all the way. But the problem is- I’ve never reached orgasm because I don’t “feel” things how I should. I’ve done lots of stuff but it’s like I have NO feeling down there. Normal? Anyone else?

Everyone that has touched me couldn’t do anything for me. It’s not the partner, it’s me. I don’t regularly masturbate and I normally don’t want sex. But lately I’ve opened up to the idea of it. What if I don’t finish? What if my body doesn’t react how it’s supposed to?
