Anyone else's husband won't have sex with them?

In the past year, I've only had sex 8 times...EIGHT TIMES. And when I ask for it, try for it, even greet him at the door with lingerie. I get nothing... I've even asked him if he was gay, he says he's not. So then what's wrong with me?! And I know he's not cheating.. so what the hell is going on? Anyone in the same boat?!

Being rejected over and over just makes my self confidence horrible, and honestly I'm about to give up on this marriage. I've never felt so alone and so bad about myself.
