Viking, I would be honored to have you in my field!
Glad you're liking the rotation. We have one male L&D nurse where I work (he started in Post Partum) and he gets along with everyone well. He's only had a few Pts refuse care from him since he's been here (over 10yrs).
To be honest, I don't think there's a lot of male interest in OB/GYN. There's actually a thread in the male nurses forum, I think it's called "Are you man enough to be an OB nurse" or something similar. Might wanna check that out.
The one thing I can warn you about being a student nurse (male, female, tranny, whatever!) is that in L&D, when crap goes down, it goes DOWN. So don't be surprised if the polite, helpful nurse who's precepting you basically shoves you out of her way when something's going down.
