Sex is different

So my boyfriend in bed is all about my pleasure like he'll be down there for like 30 mins let me blow him for maybe a few mins and then we're having sex (btw I would blow him longer but he'll start opening the condom). Well for the moment I'm living with him and his 2 roommates (long story) so I understand why we don't have as much and as long of sex like we used to (his roommates, us being tired, etc) but lately its been when HE wants to have sex or I have to try and beg it out of him and he seems to be more focused on his pleasure rather then mine. For example a few moments ago I just gave him a 30 or so min blowjob and I asked if I could ride him but he said no so I moved his fingers to my clit and he moved it away and goes no so I go "I have to do it by myself?" Him: "yep" so I did and he goes "you're really masterbating?" So I stopped. After he was done he got irritated that a spot of his cum got on his shirt. Or when I do try/beg and he says no he'll tease me and do the touching but goes okay calm down and leaves...like wtf?? I'm not really sure how to feel about this...

I'm not trying to sounds selfish its just seems really odd to me (also before this I've focused on his pleasure just as much)
