He told me I’m his bitch from now on?!

So last night I was doing my best to ride him and was getting tired and he would tell me to go higher and faster which I couldn’t anymore and was going at my pace, and he called it over and I was sad and he came back into the room telling me I’m going to be his bitch from now on, and we been trying for now up to 5 yrs but I don’t have a high sex drive like he does all the time, and when he was doing me the condom broke and I liked the way it felt, so I’m thinking maybe getting on birth control might help me get in the mood more to be able to feel him?
