"A feminine woman deliberately does things to make her man happy. (I know, this is the foulest heresy these days. It's a fundamental tenant of feminism that women must be stingy with love)."
It's an odd one. OTOH you say you owe women nothing, on the other you want a feminine woman who is striving to make you happy and the implication there is that you feel a woman owes you something, but not vice versa. There are many definitions of femininity and I don't have time for that discussion right now. I'm intrigued though that for you it's linked to pleasing a man. My last boyfriend was happy with beer and lots of sex. He liked a woman who could drink a pint and appreciated the fact that horsewomen enjoy athletic sex and tend to be very inventive. But those are not things traditionally associated with femininity. Plus, we had a very reciprocal relationship. It wasn't about me changing who I was to suit him - we both enjoyed doing things for each other to make each other happy.
"Think of your grandmother. Or her mother maybe. She very likely displayed many feminine traits. And probably was quite happy."
Well my grandmother was deeply unhappy in her marriage and felt very thwarted. My grandparents' marriage was not a happy one. Her mother was in service. I don't know a great deal about her life but I doubt scrubbing floors is the one true path to delight.
"you'd better pay attention to men's preferences, lose some weight, put on a happy face, show some feminine qualities. Complaining that men's preferences are unfair or unrealistic will get you nowhere."
I have a BMI of 19. I'm very happy with my health and appearance. I love my body exactly how it is and have no intention of losing any weight, thanks. As for a happy face, if a man has the personality of Bill Bailey, I'm more likely to be happy. If he's demanding, odd, thinks he owes me nothing and I'm there for his pleasure, I'm likely to be grumpy and will also not have anything to do with him. As for feminine qualities, I am who I am. It's not an act and I'm not going to change who I am just to please some man. Fortunately some men appreciate insightful, funny, eloquent, intelligent women who know what a socket spanner is for and aren't afraid to use it. As for the age thing? Well realistically I tend to look around 6-10 years max either side of my own age. If men don't like that, tant pis. They'll get nowhere with me.
