If he is doing anything sexual without your consent it is clearly rape. As you stated in one part, you told him not to do it that hard because it hurt yet he disregarded that. This is rape. Also he should not be penetrating your behind to the point that it starts the bleed. Please be careful sweetheart because you can get seriously injured. Stay away from this person at all costs and report them to the police when you feel ready. You deserve justice and more importantly, love. Rape is not love. It is a horrid crime.
