Sonic, we don't know your relative ages, how long you've been married, how long you knew each other before you got married, if you've ever had a mutually enjoyable sex life, what previous experiences/relationships the two you have had, etc. All those facts would be helpful in determining if you've got a situation that's developed over some time, or if you and your wife married without determining some very basic compatibility issues.
Let's say that you and your wife are younger rather than older, have been married not long, didn't know each other that long before you got married, never really had a mutually enjoyable sex life before you got married, and didn't have many experiences/relationships before you got married. If that's the case, then you have a lot of work ahead if you're going to make a go of it.
If that's not the case, you'll still have a lot of work, but at least you'll have some baseline success that can help provide motivation towards getting things back together.
When I was in my 20's, I knew a well-endowed guy, he fell in love with a very beautiful and very petite Asian woman, she was from a strict family and virginity before marriage was the watchword of the day. It was, unfortunately, a disastrous wedding night and a short-lived marriage. Both moved on, and are now happy.
Money is probably the worst potential danger in any relationship, but sex is a close second, I'd say.
If you want to return feedback, that would great.
