Does masturbation not feel like anything to you?

It works just fine with the clitoris, but when i try anything penetrative it either hurts, is mildly uncomfortable or the sensation is so mild i might as well be doing nothing. I managed to orgasm once penetratively, but it was uncomfortable after I finished and I still had to rub my clit to get off. I tried a really long but slender eyebrow pencil today to see if length was the problem and if i was missing my g-spot, but… nope, whatever it bumped into back there didn’t feel like a g spot and the pleasure sensation was pretty mild. Does this mean penetrative sex isn’t for me? It didn’t help i was really nervous.
