The only term I could think of is defeminization.
It seems like most people understand what emasculation is and the things that cause it.
What are some examples of situations that can cause the feeling?
Edit: changed effeminization to defeminization.
Nursing
Childcare
Some leadership roles (I’ve only had one female CEO but she was great)
Hospitality
Charity work
Teaching
I could probably think of more. Urban design. Basically anywhere that requires considering humans, as opposed to cold technical design like… designing network cable runs in an office building for example.
I could be wrong here, but as a man those are areas that I personally really appreciate feminine qualities.
What do you mean ‘feminine’ qualities? Like you actually believe in gender roles, or stereotypes?
