Immature Boyfriend

I had sex a week ago with my bf, and it was my first time and it really hurt. I started bleeding and he noticed and was really disgusted. He stopped and got really angry at me, and left. I try texting him but he won't text back because he said "I ruined him" because I bled on him. He thought it was my period and I tried to explain it wasn't but he won't listen. All his friends know and he told them I tricked him into sex on my period. UGH! I hate men sometimes!
