Photography: Manners and models
Keep your manners in with your models. Some models are not comfortable with you touching them. Particularly if they 
are scantily clad or nude. ALWAYS ask before you touch or preferably find another way to show them what you need. If you you need them to drop a shoulder or move a leg tell them or show by using your shoulder or leg. If the model knows you and there is trust she may be fine but do not assume anything. If you ask if you can move an arm, or adjust the hair or the like and she says yes, make sure you watch her reactions to ensure she means it.
It is OK to tell her she is beautiful and the poses are wonderful but don’t flirt. Be professional. I guarantee that your pictures will turn out much better. Always ask them to bring a friend with them. This is for both of you. The friend should not necessarily be in the room but with hearing distance.
If you are shooting nudes or glamor make sure that you have a private spot where she can dress and undress. Have a robe available so that she can cover up when you are not shooting. Some may not need something like this but by having these things available and respecting her space the comfort factor will increase dramatically.
Make sure that she knows that if she is not comfortable with anything that you are asking to say something. Also, make it your responsibility to observe if there is discomfort and change what you are asking.
Manners, even something as simple as a pleasant greeting, can go a long way to smooth any working situation.
