Owys after Sex

Does anyone else get irriatation down there after sex. I've only been having it for about 3 months now just off and on, but damn he tears me up down there even if we go slow. I've went to the doctors and they are just hymenal tears and what not, any suggestions on how to avoid these? They aren't painful during intercourse just visible and itchy after words, although if I give it a few days it heals up just fine. But this has happened to me like 3 or four times now.
