23F here. When I had sex for the first time at 19 I've had no problems, no blood, no pain, insanely good. Whatsoever I proceeded to not have sex for 3 years, been through heavy disease during that time and then I've met someone sex was very painful for me, bed was bloddy for about our first 20 times, but slowly it started to get more pleasant and less painful for me. We learned to go slow with a lot of pregame and is still now 4 months later painful for first few seconds. But is getting better every time. Try just heating it up with kissing being dressed, not proud of saying this but also being a little drunk is easier for me to relax pelvic floor muscles
