Period sex

Sami
I wear a softcup (menstrual cup) and we decided to atleast try to have sex with it on and he was dead set on still wearing a condom and i was fine with it. After we had sex he went to the bathroom to pee and throw away the condom and there was a little blood on it. Also his sweat shirt that i guess was kinda under me had some blood on it. I was so embarrassed but he didnt care but we both decided to not do it again. Has anyone ever had an experience like this?
