I have been living in Australia since the age of thirteen.
In that time, I have become accustomed to the idea that any statement or proposal by a man to a woman, say "uhm, what are you doing for lunch?" or "wanna go get a coffee?" will be construed as being 'creepy', 'sexist hornbag' 'sexual harassment I'll report you' etc. This is a completely paranoid, unrealistic construct.
I have had one 7 year long relationship with a woman in my twenties.
Clearly I have an extreme lack of self confidence when it comes to the opposite sex. Perhaps that came through being raised as a fatherless bastard by a feminist mother incapable of long-term relationships. Experiences that others would shrug off would affect me deeply. I'm overly sensitive and prone to drug abuse, simple in an effort to tone down the painful intensity of experience to a level I can handle. Even pleasurable sensations are painfully intense.
I have come to accept that the way I am. I have no desire to have a family, and even if I never had another partner for the rest of my life, that's OK too, I reject the idea that because I am a man, I MUST have a woman or I'm a loser. If it happens, it happens.
As for the double standard, like one of the early posts pointed out, at the beginning of the 20th century, women were expected to be completely passive and man completely active in that regard. I think with the breakdown of first the extended family, then the nuclear family (50%+ divorce rate) women are free to ditch their partner when they imagine a better alternative. (another partner, or sole parent, or bachelorette, or lesbian etc)
There's actually a very good reason for women to do the courting, rather than the men: Women are afraid of being raped -- men are afraid of being rejected. So if men were more passive in courtship behaviour and played it cool, and women more pro-active, perhaps women would feel safer? Would they actually BE safer?
I don't know.
