Rape. When she says stop he should stop. A lot of people enjoy it rough and will sometimes teasingly say "stop" but not really mean it. It is very important to have a key word, other than stop, to say to your partner when having sex and you want then to quit.

He was asked to stop. He did not. That is rape

Yup it’s rape

This one is hard. Some may see it as rape & others wont

I like it rough sometimes ( sorry tmi) and when I tell my boyfriend to stop, I don't really mean stop. More like I want him to take control and pin me down.
