"Female Staff" Bingo! You hit the nail on the head!
When I worked at an agency, we would host photo shoots for models / potential models in which alot of them were between the ages of 15 to 23 females. Our photographers usually were male professionals, but we always had either I or another young lady whom is a pro model be the "photo assistant". Not only could we make you feel comfortable, but help give direction to the model and assist the photog with reflector, hair, what not.
I personally don't do shoots alone unless I know you, bottom line. Even then, people know whom I am with at what time and where.
It's a touchy situation, and not black and white, too many grays inbetween. For the most part, I tell models to have "assistants" with them. Not boyfriends, not dad's or mom's, but hire a make-up artist to come along, or get a friend that is a model.
Now, I do have to say that my husband has come along on one or two of my shoots with new photographers, and guess what, they love him!! Held the reflector, helped carry the equipment, kept is mouth shut. But, I also know that he is proud of me and what's me to do well, not jealous at all, but I am also lucky.
OK, that's enough of that, rambeling!
