Am I able to wear tampons?

Bluey

I've been trying to wear tampons for five years, on and off. I read the instructions many times to understand it. I know you have to pull downward. I tried pulling it as far as I could. I can still feel it no matter what if I'm standing or sitting down. When I walk its still uncomfortable. I've tried on my heavy days, light, and when I'm not on my period. I tried using the smallest tampons that are made. Still nothing. I will be able to feel it no matter what. I have painful sex too. I go slow on that. Even my right hipbone hurts. I cannot tell if it's actually my hipbone or my tubes being in pain. From my hip, I think it's related from having sex. It will hurt when I have sex or any other random time. I don't understand what it is. I went to the doctor for my hip and she said it was nothing.

Does anyone else have this problem or is it just me?
