A client came to see me recently to talk about an issue that was upsetting her. She is 39 years old and has been married to a man the same age for about 15 years. Neither had had many partners before they got together.

They've had a good sex life but in the past few years she has felt the passion was missing. She was getting bored and was thinking about what sex with other men would be like. She had no intention of cheating on her husband and when she read an article about a swingers' club in their area, she was curious.

When she suggested the idea to her husband she was quite surprised that he was not upset. On the contrary he seemed quite interested. It took them a while to find the courage but they finally gave it a try.

They both liked it and it improved their sex lives for a while. But the one thing my client had not expected was feeling jealous when her husband had sex with women who, in her opinion, were better looking and more sexy than she was.

Although she is an attractive woman she began to feel more and more insecure. She decided not to take part in swinging any more but her husband is now disappointed and blames her for suggesting it in the first place.
