Husband Not Physically Satified, So I'm Not Sexual
My husband and i have been married almost two years, since we were married i have gain some weight (20lbs). I am feeling insecure about how i look and my husband has definitely noticed. Without a positive effect on my self esteem from my husband the problem is just getting worse. I find myself wanting to be intimate with him but he always has an excuse. we are down to about twice a month. how do i spark things back up in the bedroom and our relationship while i am trying to size down. I feel like this could be a relationship ending problem for him and i want to recover.

You sound very self-aware, and even small changes to one's body can cause damaging blows to self-esteem. Have you shared your feelings with him? What are his excuses? Maybe they're not excuses, and maybe you're sensitive to the weight gain, but it's not the issue, or at least not the whole issue.
I would tell your husband that you are working to lose some weight, for both of you, and would like his support and encouragement. This will help if the weight is the issue, but it may also allow him to talk about any other issue that could be at the root.
Yes Really, I'm agree with Gail statement.... I think her husband having some another problem like Erectile Dysfunction..... Thanks!
