From an expert on "the etiquette of open marriages."

"'I'm a class act in infidelity. I was very clear with my husband from the outset that I would do as I saw fit for myself, and it has nothing to do with him – it's not a sign that he is inadequate in any way. I knew exactly what I was getting into marrying him and he's delightful, kind, supportive, a good husband, a wonderful father and a really nice man. I didn't expect him to be all those wonderful things and a sex god.' In fact, she says the curious thing is that her husband doesn't take lovers, even though she wouldn't mind. 'He isn't a very sexual person,' she explains. They've been 'very happily married' now for nearly 25 years."
