Í've flown with a few female loadmasters; couple of them were quite comely, actually. They both started in the military.
That said it is a hard hard way to live. 48 hours with the plane at times. You may cycle through 5 or 6 crews in that time, but the loady hangs on, getting stinkier and stinkier.... Awful things happen to your body after that much time airborne....
To me the best FA jobs out there are in the larger corporate jets. Met a girl in the James Joyce in Paris last month, flew on Gulfstreams for the company that owns Victoria's Secret. (Yes, her secret was safe with me....) She was touring Europe out of her home base in Ohio.
