If a boy is cool with period sex should I hook up eith him?

I have been hooking up with this guy for a year now and I’m supposed to see him tomorrow but I started my period. The first time I had sex with him I was on my period too and he knew that and was cool with it. A couple of months ago we were having sex and after we finished he told me I was bleeding. It was weird because it wasn’t my period, I just bled for a bit and then I was fine the next morning? I still feel weird about it but I’m glad he’s mature about it. If he’s ok with it should I be too?
