Sex is unbearably painful?

I was wondering if anyone has experienced similar issues to me. For as long as I have been sexually active, sex is unbearably painful. Sometimes all of the muscles clamp up, but most of the time, I experience an extreme burning sensation. My partner and I do not have any STIs/STDs, I do not have a UTI or yeast infection. There has always been a sharp burning during intercourse and even fingering. Sex is not pleasurable at all, I don’t enjoy it. It makes me feel like there’s something wrong with me. If anyone else has experienced anything similar, please let me know!

Edit: My boyfriend and I use a ton of lube, so I do not think this is the issue
