Help!

I live with my boyfriends grandma and he lives next door with his parents! We don't get much alone time at all, I give him blow jobs often to keep him satisfied and I've always done it as often as I can, but I get upset when we can't have sex because I want to be satisfied too! How do I explain to him why I get upset about it when it makes me horny to give him one and I don't get anything back?
