Can it be rape if you’re married

Ok so I’m having a hard time with this, the other night we were having, sex doggy style, then all of a sudden he rams it up my ass without my consent, now I fall to the floor and tried to push him off and he just grabbed my arms and pinned them in my back while he kept going, I told him to stop but he said since we’re married he can do what he pleases I’m just having mixed emotions and don’t know what to do I love him but at the same time how can he do this now I’m afraid of being with him for this very reason is it rape I mean we are married so I have to take it
