Speaking from experience, this is a tricky subject. I was not happy with my husband in bed at all. We were married for 4 years. I went and slept with another man, and the sex was great. My husband had no clue. Now, there is one problem the sex with my husband is even worse now then it was, and I feel absolutely horrible. So, as far as I am concerned, please think before you do anything. It could end up hurting your marriage even more.
