People are people regardless of situation or role and their responses may not be in any way linked to the lifestyle. I agree with Archeon that they are simply being polite and unless any of them step over what is a very delicate and often movable line and become harassing I don't see that you have a problem. Bear in mind, however, that the almost universally accepted definition of 'harrassment' covers any behaviour that the 'victim' feels is harrassment so the position of that line is solely in your control - if you feel that any of them are stepping over that line, I would be sure to tell them - in a polite manner, of course.

To be honest, I think many men often feel that they are walking on eggshells with regards to talking to women. Instincts scream at them to be 'manly' - decisive, strong, protecting - but some women don't want that any more. So they have to be careful to not cause offense. Dom men may be more susceptible to this than others because they tend to live with women who *do* want that manly thing and therefore it is more of an effort to switch it off when, for example, you are talking to a Domme.
