I would qualify the advice that the wonderful denu gave to fit your situation!
It is wise to check and investigate any advice you get before acting, but everyone I know who has a mentor has only one (one that they actually refer to as their mentor anyway) - in my opinion they are as well off asking questions of that single mentor and then discussing things with friends of theirs. And looking up the definition "... true mentoring is more than just answering occasional questions or providing ad hoc help. It is about an ongoing relationship of learning, dialog, and challenge ..." I wonder how many actually have the time and/or luxury of more than one "true" relationship of that nature - my experience is that being a mentor is just as much hard work as having a sub but without the fun element (which is why I wouldn't offer to be your mentor, for example!).
In this lifestyle subs are (often) taught to be open about their feelings/problems/fears/desires/etc, but I am not sure that it is a good idea for everyone to discuss all aspects of their relationship on a forum! In fact I am more than aware that for some people to ask even a relatively "tame" question "in public" like this takes great deal of courage (especially as this forum does not allow anonymous posts). The bdsm community is sufficiently large that there is a high possibility any question you have would have been answered and probably discussed in depth somewhere - but it can take a great deal of time and effort especially when there is more than one possible answer (and as we all know every bdsm relationship is different so that happens frequently). It IS much easier just to ask "someone in the know" and hope that their knowledge/experience is applicable to you - but if you do please be "risk aware" that it is just their opinion/point of view.
