Are "Masculine/Feminine" and "Mannish/Womanish" forms of sexual discrimination or not?

I used to think that all girls should be feminine because I believed that it made them look more attractive. (Ex. Wearing skirts, makeup, and having long hair.)
However, after I talked to my foreign friends and learned more about various cultures and their ways of thinking, I started to think they might be gender stereotypes and I tried to get rid of the prejudices. (A girl who I was interested in broke my bias by snoring loudly like an old man does. Love is blind haha)

Although I don't have a lots of female friends, most of them seem fed up with being girls because of periods, pregnancy, makeup, and so on. They say "I wish I was a man" "All men should experience being girls". So, I thought that they didn't like sexual discrimination. But they don't hesitate to tell me something like "You're womanish", "Be a man". I find that interesting.

I know most of women like masculine guys but I'm not that kind of person unfortunately. I feel that I should try to become more popular with girls but I prefer being the way I am. (It doesn't mean I'm gay, btw) Of course, I want my friends to be the ways they are regardless of gender. That's why I don't want to judge people's behavior, personalities or fashion by it. (Hope my friends won't either but that's their call)

Just a few small mistakes with consistency, but easy to understand (I could understand completely). I tried to show you changes for the best possible grammar, but even native English speakers can make these mistakes sometimes. 

I totally agree with what you said, and I hope you find a girl who likes you for who you are, and doesn't try to make you more masculine if it makes you feel uncomfortable. 頑張ってね！
