Bottom line is, sex is for both partners. If she doesn't want it, you aren't doing your job. If she's stressed, do more around the house. If she's just not interested, find out why. Is it lack of desire? Lack of energy? Lack of time? It's about pleasing your partner as much or more than you want to be pleased. Biology dictates that men and women have very different views of sex and pleasure. Women and men both need to take the time to learn what their partner wants and needs. It isn't just about her pleasing him or the other way around. It's mutual or it is nonexistent. Sex is less physical than it is about the connection between the partners. Make jokes if you like, but a satisfying sex life is very important to a marriage. Not just the amount of sex you have, but the quality of it and how it makes you both feel. As for not getting any and cheating, that's crap too. Cheating is almost never about just sex. It's about deeper issues and how they are left to fester. You made a commitment to each other. Honor it. Men, find out how to please your woman. Seriously. Women, do the same. Search for the real intimacy that you share and make your sex life better than it has ever been before.
