I have never really experienced this type of predudice. To the contrary when I tell women I am a nurse, or when I was in school a nursing student, I always recieved respect.
The only comment I recieved from a women while in nursing school was another student who was complaining that all of the patients would be calling me "Doctor" instead of nurse.
When I was in school I was still single until my last couple of semesters when I met my wife. It made dating women easier if anything if you want to go there. I should think you would be making it work for you, not feeling somehow emasculated in the eyes of women you converse with.
As far as other men go, Some of my older friends introduce me as a "male nurse" but I think that is a generational thing.
In my other profession which is "manly" by its very nature, I have not heard one peep about me being a nurse, to my face or otherwise. To the contrary, the guys I roll with like having me around especially since our medic got hit.
