So if a woman's most intimate emotional relationships are with women and she is also capable of being sexual with them, why would she continue to call herself heterosexual? What could she possibly get(or give) to men that she can't get(or give) to her female "friends"?
The problem I'm having getting your point is, women who classify themselves as heterosexual and who are in a positive romantic relationship with a man tend to characterize that relationship as their most intimate adult emotional relationship. Women who classify themselves as heterosexual who are not in a relationship with a man, tend to yearn for one with an intensity that they do not yearn for a friendship with a woman.
I'm going to do a feminist on you.
Sources?
Women often say that men are incapable of emotional closeness. So how can they be having a deep emotional relationship with one?
Further women tend to reveal their more intimate concerns and needs to other women rather then to their husbands. Whereas men rarely exhibited that sort of intimacy with other men.
Here is a exerpt from an article I found...
"Gender differences in friendship are particularly marked and, over the years, research has increasingly pointed to the value of a special relationship or confidant in adjusting to the stresses and strains of later life. For women especially, this is also a life course issue in that the presence of a confidant or close friend has been found to be important in terms of social support as well as in the maintenance of psychological well-being and mental health. Moreover, rather than fulfilling this need for a confidant within the marriage relationship, women tend to look to other women or an adult child for this kind of support. Men, by contrast, name their wives as their main source of emotional support and the only person that they talk with about personal problems and difficulties."
