Pain with sex?!?! TMI sorry.

I’m 19 years old I started having sex when I was 13 I’ve had a total of 8 sexual partners some of those being women. No matter the size of the penis real or not. Long, thick, short, skinny, anything that penetrates sometimes even fingers it’s sharp shooting pain like I’m being stabbed form the inside out. I try to deal with it but 9/10 I have to stop because I’m in tears. And I can’t take anymore. Does anyone else have this problem? Should I be worried? Any tips on how to stop it or reduce the pain?

Thanks in advance!
