No sex for over a week...

My husband has been seriously lacking on the sex lately... He doesn't try to come on to me at all! I wanted birthday sex so bad about a ween ago and half way in to it he's not even 100% hard and doesn't seem into it. Completely silent and seems uncomfortable. He told me he was really full but I don't believe it. Maybe 3-4 times this month I've had this problem with him doing this... I try to talk to him and he just says he's hott, tired or too full. I'm like wtf is wrong with me, are you not attracted to me or do you think I'm fat or what the hell. I'm so freakin horny lately that I'm resorting to porn and using my vibrator when he's not home. I want him so badly to just pound the shit out of me and be kinky and rough but he won't... He used to be SOOO horny like sex every day and now nothing. I don't know what to do any more. 😔
