Sexual Cemetery

Why is it that I can’t have sex anymore. I shouldn’t have to ask for sex but it doesn’t matter because we never have sex anymore. I’m tired of going to bed horny every night when I share my bed with someone. I’m so sick of this. Like I make sure our son is put to bed and everything by 10 so I can have an hour of time with you and you never want to have sex anymore you don’t kiss me or anything. What should I do? Do people really end relationships over sex
