As I woman, I would also have a problem with my hubby shooting nude females (and I also wouldn't care to marry a doctor, for that matter

). My husband and I dated seven years before getting married and he knew about my 'jealous tendencies' from the start and it's something that we both have worked on. They have never been a problem, because we know how to work together. But there will always be things I am not ok with- him working with naked girls is one if them... Art, profession, any reason.
No one is perfect. You will never find the perfect person, but you can find someone perfect for you. She may not be it. If you not willing to change your art form up a bit for her, and she's not willing to try to be a bit more understanding of your work, maybe it's time to move on.
I didn't read all of the replies, so you may have remedied the problem already but this is just my two cents. Good luck!
