Maybe I'm Not That Attractive

Okay, so there's this thing going on: me and my boyfriend, we had sex for the first time in January. Thungs were good, I'm the one who's always horny, but you know, he kinda follows, we can deal with it. Two or three weeks ago, things started to get "weird", I mean... we slept together, then I woke him up for some morning sex and he acted like I was forcing him to something. He literally woke up, had a 15 minutes shit, I mean, he refused a blowjob, so we had sex and he got back to sleeping. I invited him to shower twice, he declined. Today, I went to his place. We were home alone, watching a movie, I was not in that horny mood, but then he came with all those hot kisses and all. Ended up getting his so desired blowjob and left me. He literally just had the blowjob and then acted like nothing happened. Sometimes I feel like he just doesn't care and I'm being some sort of used. I'm feeling unwanted, undesired, all those not-wanted stuff. It sucks. I feel like I'm not enough. Anyone?
