AITA for not being attracted?

Am I being unfair?

Ok so I have a boyfriend it's fairly new about a year or so well recently he started living with my and my child. Since then we've had a few hickups but overall it's been going well. One of the hiccups involves drinking he would get drunk and horny but mean you know just...sexually? I think that's when it started as it's happened a few times since we've had a talk and he stopped. Hes a good guy my child loves him he's good to me. I don't know why but recently during sex and normal day.... I'm not attracted him? I don't know he's cute but he isn't I wanna throw you on this bed and stare at you lovingly all day.... Is it just me? Am I broken? He's not my usual type and I do love him but why can't I just fully lock in? He hasn't been taking care of himself lately.... Is that it? I really hope I dont sound horrible saying this
