Painful sex


Does anyone know why I'm in pain when I'm having sex? I know its not an infection because I've had nfections in the past and I know what they feel like. I don't really enjoy sex because it's painful for me. Ive been with different guys so I know it's not cuz their dick may be too big lol just wondering if anyone goes through this too. I like the act of being with a guy I just wish it wouldn't have to be painful for me
