So do women, in general, have masculine energy within them?
Yes, absolutely.
Even men have feminine energy, except the masculine side is more prominent whilst the form exists in its latent form.
The other difference is how people balance their energy. Some people are hyper-masculine and some people are hyper-feminine.
Ideally, a man should not be EXTREMELY masculine.
Because too much of one thing isn't a good thing. The same applies to women—the equilibrium of energy is very important unless you want to be super aggressive, that is.
