My mom is a nurse and often discusses the real need and opportunity for male nurses. Some men feel more comfortable having a male nurse for certain care needs. There are even incentives such a scholarships and grants for male nurses at some nursing school programs.
There is nothing at all wrong with a male nurse, of course. In fact, I think a lot of men would feel more comfortable with having a male nurse for certain things that they would feel embarrassed about with a woman. We need diversity in the workplace. There is a real shortage of nurses now, so you are pretty much going to get hired. It’s a good, steady, dependable job.
It's wonderful for a male to become a nurse, and I have noticed more and more male nurses in my local hospitals. There is also some research to suggest that when males enter a female-dominated profession, wages improve for everyone. So, the more males we have in nursing, the better it is for females, too!
The medical field is so vast, and society is more diverse and tolerant, now. The demands of being a doctor might not be what any man or any woman may want for a career. Nurses have quite a lot of demands placed on them as well, along with long 12-hour shifts, but they don't have to maintain a business as say a doctor might. My son wants to be an anesthetist, but also jokes around sometimes saying that he wouldn't mind being a "Murse" as well. "What's a murse?" I asked. His response: "A Man-nurse!" I guess that is his way of approaching the the gender-related issues so archaically applied to the word nurse.
Male nurses have been around for a long time. With the medical services field standing as one of the fasting growing fields of employment - if not the fastest growing field - no justification is needed for anyone to pursue nursing except an interest in doing nursing work.
There are reasons not to go into nursing, but they aren't gender-oriented reasons. You shouldn't be a nurse if you don't enjoy helping people one-on-one, working in a medical setting, taking responsibility for other people's well-being, etc. This is a burgeoning field, but that doesn't mean it is for everyone.
You should pursue nursing if you are drawn to the work.
It is very outdated to think that nursing is a profession that is not fit for men. It is also ironic that we think this now because there was once a time when people believed that women were too delicate to be nurses.
Anyway, it is interesting that we see nursing as being feminine because it has to do with nurturing when we say that being a doctor is alright. They are both essentially trying to help people heal. So no, I do not think this is bad.
