My boyfriend isn’t sexual

I’ve been with my bf for 7 months now. First 5 we didn’t live together. We come see Friday, Saturday and Sunday. I would give we do something but If i wanted to do it twice day he would tell me no. “We already did it”. Now we’re living together. We had sex twice for about 3 minutes each time. Then I’ll finish him with hand job. Most night he would tell me he was tried or he had dirty has he shouldn’t be touching me (he does work in car shop tho) now he only works two days week. But still he doesn’t like touching me or when I try to do anything anything with him he tells me no. I talk to him he tell me he brothers are down the hall I’m not comfortable. He tell me we can take drive go somewhere have sex. When I ask if he tell he’s tried. At this point I just stop trying. I’ll just go watch porn instead of asking him
