Femininity is something people do, not something inherent to being a woman. (Also, with regard to the way you posed your question, technically a man is a woman with different bits, not the other way around.)

I don’t know how to split out socialization from biology, honestly. Are you asking what strengths are considered feminine and are also admired by men? Probably being able to handle physical pain, being good at organizing, endurance in the face of adversity or grief. Ability to read a room, pick up on cues, make people feel comfortable.

Are you asking what strengths are admired by women, what do we consider a strength of women? You will probably get different answers from different women but I think women are often better able to consider a whole situation rather than focusing on one part of it and messing up another part; and that we are usually better at handling physical pain without whining.

If you are asking how willpower feels for me as a woman, though? In terms of deferred gratification? Probably about how it feels for you. Sometimes easy, sometimes it sucks.
