I don't think we always need the masculine at all. I think completely feminine people and relationships are wonderful too.
I love the line at the end, however, about how being feminine is one of the most rebellious things we can do today. I agree. My profile here is pink. Ten years ago, I'd never have admitted it's my favorite color.
I too like powerful, strong, and masculine people in my life. But I'd be equally happy with someone very feminine.
