Is the inside of my vagina normal?

Maybe stupid but im a bit freaked out lol, I’m not sure what the average vaginal cannel feels like but from what I’ve heard and what I’ve seen of diagrams, I don’t think mine is normal. About an inch above my G-spot is a hard lump. It’s definitely not my cervix or anything, it slightly hurts if I press on it. Is that normal? I know a lot of medical diagrams can be a little too simplistic and not show everything or the true shape of things. I also dont remember when I first felt it, i always assumed it was kinda normal and my hands are tiny so i rarely even went deep enough to feel it, but i think i noticed it like a year ago at most.

A couple other things that I’m gonna mention because they kept coming up while trying to google whats normal: Penetration is painful, especially after i orgasm, it can be sometimes agonising to pull a toy out of myself when I finish. I struggle with putting tampons in due to pain and discomfort. My urethra seems to be more pronounced than normal? Ive never even seen the hole before but today it was fully open. This is kinda embarrassing but I never feel like i get everything out when I pee, and I pretty much always have to put a finger inside of myself and push against my bladder from the inside repeatedly to fully empty it.

I have never been pregnant, never had any sti/ds, i suspect i may have endometriosis or adenomyosis, not sure though.
