Would it help you to find some things you really enjoy doing and engage in those activities? I enjoy dancing and showing my dogs. I take a dancing class one night a week and I am involved in a dog club. I also enjoy sewing and have made a whole room in my house for just that. When I get overwhelmed I go in there and work on any number of projects.
I'm not saying you should ignore your H, but take it from experience, begging, whinning, fighting about it won't change the "no sex" issue.
