Ambergold, you make interesting points. You list the problems that women face and deny the "inner female," and go on to say that crossdressing is a way for us to escape the problems that men face. But I'm afraid that while you were listing the negative social implications of being female and the responsibility of power and privilege of being male, you have forgotten the virtues of femininity. Women may not (generally) have the physical "power" that males have (an overrated thing) but in their softer frames exists a subtle and mysterious power which is greater and more beautiful than the brutish muscle of a macho man. Femininity involves such things as empathy, nurturing, healing, grace, and all manner of such things which should be regarded as general virtues rather than signs of weakness. Females have as much responsibility as men do. As for social privileges and expectations, that is only a social construction which, while having real implications, has no inherent truth or cosmic validity. The social inferiority of women (which is in decline) has nothing to do with the inherent qualities of femininity, but rather the witless thinking of men through the ages.
The inner female may not be present in you, but would you deny the reality of the trans community? Are all transwomen simply looking to divest themselves of male responsibilities? In truth, they take on more hardship than any other man could ever know (that is, those who pursue transition). Gender is not black and white, but a fluid spectrum. Many great men through history have exhibited traditionally female traits, and vice versa. Think of gentle St. Francis giving a sermon to a flock of birds, or Buddha renouncing a life of wealth and war for a nonviolent existence of teaching and meditation. Conversely, think of Joan of Arc wielding a sword or Annie Oakley outshooting her male counterparts. We can choose to reject social convention (as crossdressers we do this anyway). Many of us wishing to express the inner female by whatever methods and those of us who wish we were born female would gladly take all the social discrimination, menstruation, and all other unpleasant things that come with being a woman in order to have the experience of womanhood in its beautiful and glorious entirety.
As for Reine's original question, I too am confused by the simple answers like "I just enjoy the clothes." I don't necessarily question it. If someone tells me such a simple reason, I accept that. Maybe it is that simple for them, but as always I can only speak from my own experience, which goes much deeper. Neither the simple or deeper reasons are more valid than the other, and I wish society could move forward and accept people in whatever clothes they choose to wear. If it never happens, then I will wear the clothing I want anyway, if only around the house.
