My Master has been in the lifestyle for about 9 years now, his first mentor was Domme (a friend of his) but he told me recently that there came a point where he felt the need to learn from a male perspective, there were simply things that a female couldn't teach him. He still communicates to both his Dom mentor and his Domme mentor but when he is looking for advice his first call is to the Domme, I don't think this has anything to do with the fact that she has the female perspective but simply more to do with the fact that they have remained closer.

The most important aspect is that this is someone who he can trust and who understands him, also someone who he will be able to turn to in the more distant future if the need arises.
