What do you call this?

During our relationship ( we are no longer together), when he wanted sex and I didn’t want to have sex… he still did it anyway. He even used to have sex with me while I was sleeping and I would wake up to him moaning so loud and him about to finish.

In my eyes it’s rape, because I said no. But he would always say it’s not because I’m his girl and my body belongs to him 🙄 he even did this in the first 2-3 months of my pregnancy.
