I have noted male airline stewards tend to be light in the loafers.
A high proportion of male nurses are also light in the loafers.
A high proportion of female prison guards are bull dykes.
10% of the population is homosexual according to stats. Probably higher than that.
That's because masculine men have trouble being "under" another man's authority. If I were a nurse I would be arguing with the doctor over who knew more about treatment options for a patient.

I would not last long at the job.
