Masculinity cannot exist without femininity. On its own, masculinity has no meaning, because it is but one half of a set of power relations. Masculinity pertains to male dominance as femininity pertains to female subordination.

Male supremacy is centered on the act of sexual intercourse, justified by heterosexual practice.

Masculinity is part of a binary and requires its opposite, since, in the absence of femininity, masculinity would have no meaning.

It should not be a surprise to find that s/m fantasy is significant in women's sex lives. Women may be born free but they are born into a system of subordination. We are not born into equality and do not have equality to eroticise. We are not born into power and do not have power to eroticise. We are born into subordination and it is in subordination that we learn our sexual and emotional responses. It would be surprising indeed if any woman reared under male supremacy was able to escape the forces constructing her into a member of an inferior slave class.

Recent literature on transsexualism in the lesbian community draws connections with the practices of sadomasochism.

[Transsexual surgery] could be likened to political psychiatry in the Soviet Union. I suggest that transsexualism should best be seen in this light, as directly political, medical abuse of human rights. The mutilation of healthy bodies and the subjection of such bodies to dangerous and life-threatening continuing treatment violates such people's rights to live with dignity in the body into which they were born.

Radical feminist theorists do not seek to make gender a bit more flexible, but to eliminate it. They are gender abolitionists, and understand gender to provide the framework and rationale for male dominance. In the radical feminist approach, masculinity is the behaviour of the male ruling class and femininity is the behaviour of the subordinate class of women. Thus gender can have no place in the egalitarian future that feminism aims to create.
