My Fiancie' is a RN at a local hopspital and works with a couple male nurse's she works with and graduated with and has no problem with them. so my answer would be no doing something to help people is very rewarding mentally and financially. I've even concidered going myself.
She also said that becoming a CRNA is'nt something you become right after getting your bachelors degree, you have to be a RN in the ICU for at least 2 years before being able to even apply for this particular grad school and they have very stricked requirements to get in that class....
