Practice of Dhamma and loss of masculinity
What is masculine and what is not is only the product of collective thought, consciousness, and superstition in a given culture. Note how this differs among animals, there, it (masculinity) is not a fixed, unilateral idea.

It is not worth to be caught up by fixed ideas and divide masculine and feminine, for they are one and cannot exist without each other as there wouldn't be continuity of human life as we know it.

Such clinging to polarity brings suffering.

Rather, perceive it in terms of human virtue and nature in general and transcend such limited notion. Such notions lead to generalisations, generalisations lead to prejudice, and prejudice leads to suffering, inequality.
