Lots of good examples of how the western world has been more feminized, I'll just add one to the pot:
The average* woman loves to be taken on romantic dates, to be showered in flowers, gifts and jewelry. She loves to have romantic, intimate, sensual sex, and be doted on and pampered. She loves having a sensitive partner who will listen to her.
It's not only acceptable for her to expect these things, it's considered basic "good boyfriend" behavior to provide them. If you (as a man) don't, the average person will probably think you're an asshole.
Now, let's look at the opposite scenario.
The average* man loves being adored by his woman. He loves to be showered in physical affection. He loves hot, wild, dirty rough sex. He loves blowjobs. He loves to feel in control [which she can facilitate by being submissive sometimes]. He loves the female form and it's beauty, even though he's wildly in love with her.
For some reason, expecting these things from a woman is akin to sexual slavery. Instead of being considered basic "good girlfriend" behavior, it's abusive and sexist. If you (as a woman) don't do this, the average person isn't going to look down on you, and IMO would applaud with the attitude of "you go girl!"
A feminized society is one where what women want and prefer is considered the correct, healthy way of doing things, and what men want and prefer is considered abusive and entitled.
Anecdote time:
My parents have stayed together for 30+ years. Every year for christmas my mom gets my dad a sports illustrated swimsuit calendar for the bathroom in his workshop.
Instead of belittling him, putting him down and being disgusted by his nature [of being visually attracted to sexy women], she accepts that's how he [and most men] is/are and understands that it doesn't mean he loves her any less. (I know nothing of their sex life, thank god, but it's the attitude I'm talking about).
*I'm making generalizations here. I understand many men and women are different/don't subscribe to the norm.
