Lately I have heard some discussion about lesbian women who go on to marry or live with men in heterosexual relationships. (Example: Anne Heche.) I have seen this phenomenon with a few lesbians I know. However, I have never heard of a case where a gay man decides to marry or live with a woman. Why is this? Is male sexuality more ‘hard wired’ and female sexuality more fluid? Do women benefit from heterosexual relationships more than men do? I did ask a gay acquaintance about it, and his reply was that women are ‘just too demanding’ in relationships. Can anyone help shed light on this differential?
