Boyfriend masturbating!

I recently moved in with my boyfriend of three years, we’ve been best friends for 7 years; 4 months ago. I moved 1,200 miles from home to be with him. Obviously I love him right? Haha anyways we’ve only had sex about 5 times since I’ve lived here. And I want more sex trust me i do. Who wouldn’t ? One night I woke up at 3am to see he wasn’t by my side or in the bathroom. So I peeked around the corner in the living room and he was masturbating I don’t know why I was so hurt by it. Maybe because I feel like he doesn’t want to have sex with me? Am I not good enough for him to come in and wake me up with some surprise sex? So I brought it up to him the next morning and he freaked out on me. Saying maybe I shouldn’t be spying on him and I wouldn’t have gotten hurt. And Last night he was masturbating in bed next to me while I was sleeping, it woke me up. Once again I brought it up to him and he got defensive and freaked out on me this morning. When we have sex it’s literally 3 minutes long. He cums so fast. I’m obviously never satisfied. I’ve never came when we’ve had sex. Am I just overreacting by being hurt by this? Should I not be mad that I don’t get satisfied? I don’t know what to think.
