ADVICEEE

So my period ended yesterday morning. My boyfriend and I decided to have sex tonight and he decided he wanted it rough. The first round we didn’t use a condom, but for the second round we did, sounds weird, but that’s how he likes it. Anyway, he called me after I left and was freaking about because there was blood on his dick and there was some blood on the condom. When I got home, I noticed I was bleeding some, but not a lot. I’m not a virgin and my period ended. I don’t know how to explain it to him. Help?
