I had actually posted a really long reply to this yesterday and as I was typing it deleted itself! Pissed me right off!
Anyway, here goes again. I was engaged for two and a half years. The last year we may have had sex ten times. He made me feel so ugly and fat and just plain gross. He always had some excuse like "my head hurts" or "i'm too stressed out" (being as I supported his ass I dunno what in the world could have stressed him out!) or "i'm too tired" (from what?)
he had my self esteem so ruined that by the time I left him I did not even date for two and a half years after the fact. It has been about seven years and I still do not have my self respect back.
I do not wish those feelings on anyone. But, I do know exactly how you feel. Of course, we had some underlying issues (at least he did) so that is why I finally left. So, I am not by any means saying to leave your husband! You are married and commited and I am sure that you love each other very much, you just have some things to work through.
But, don't let it go on like this! You have to force him to do something about it before you suffer permanent damage! I know that sounds severe, but it is true.
So many people say that men thing about sex all day and they always want to have sex and blah blah blah. Well, let me tell you what: if that is really true for some men, then please send one mine way! No man I have ever been with could ever keep up with me! So all of this men vs women stuff is not true. Maybe in teenagers or just in majority, but not true in general.
Anyway, the only thing I can tell you is the next time you sit your husband down to talk to him about this, let him know exactly how important this is to you. Explain that it is not just the act of having sex. It is the needing to feel wanted, desired and loved. And that your self esteem is going to get ruined if something is not changed. Maybe he needs to see a doctor or counselor.
As for "spicing up your sex life" (a lot of people will tell you that) there is nothing wrong with trying that, but if you are in the situation that I was, it wont work. I mean how do you spice up a sex life when your sex life is nonexistent? I even tried the lingerie and candles and whatever(along with many other things), and he still turned me down. That is definately a feeling that you do not want! And when he actually did give in, I knew he wasn't interested. Sex like that is worse than no sex at all!
So, ultimately you are going to have to talk him into getting help. Help of some kind. Maybe, you two can take a vacation or something. Even just get a hotel for the weekend and act like teenagers again!
