My wife was raised in a very conservative family and because she was concerned with being a "good girl", our sex life was very infrequent and boring. About five years ago, I put my foot down and told her that for the sake of our marriage, we needed to work on our sex life. We discussed her issues and she slowly started to change. I got her to lose weight and dress sexy. I got her to buy into more variety and the woman who avoided sex started playing with the sex toys I bought her, watching sexy movies with me and having disceet public sex. Although it hasn’t happened yet, she has gone from "no way" on a MFM threesome to saying she would go along with it if the circumstances were right.
