Unwanted Feelings Aren't Leaving !

I have unwanted feelings of being trapped. I have realized how big the world is out there and have been looking at other men and talking to men on the computer. I have not been unfaithful to me husband nor have I met anyone I have wanted to do that with. I have been looking at other men though and thinking of how my life would be if I were single. I don't know why I am having these feelings. I met my husband at a gym where we both worked. We were always more like friends and argued often until I decided to join the military.

After my basic training he came to visit and asked me to marry him and I said yes. I knew I loved him, but had a weird feeling in my stomach when I said yes. I figured I was unsure but knew most of me wanted to be with him. We were married six months later and have been married for a little over a year.

I have lost desire for sex with him and often find myself avoiding it with excuses. He is a full-time student and I know I resent him not working a little but I can't imagine what would make me not want to have sex. I have actually become more sexual feeling, I feel sexy however I feel that way towards other men.

I have been talking more and more on-line and find myself wanting to talk sexually with men on-line. I daydream about a life not married and it makes me sick.

My husband is a very nice guy and has done nothing wrong to make me feel this "lack of feelings". Please help me understand. I know it is wrong to feel this and am afraid that my marriage is ending slowly. I 'm not sure if I rushed into something that I really didn't want and now it is coming to me. I am confused, ashamed and want to figure this out. Thanks.

Anybody can offer advice?
