how would you feel if your bf lost a fight to another woman?
When I was 13, I fought after school with girl and I lost. I felt great shame. This girl was good at fighting and I was the typical nerd. We started fighting on the lawn behind the school, in a boxing posture, surrounded by screaming kids from the class. It must have looked badly, when she sat on my stomach, punched face and pulled my hair into submission.
My girlfriend knows me. We often do mixed wrestling. I don't beat women, but I do real mixed wrestling (no fake) very willingly. If she knew that I fought with another girl then she was jealous and evil as about sexual betrayal.
