^_^ of course! The desire to serve and obey is an innate quality, at least in myself. Its derived from a desire to please. And it manifests in so many different ways, including being a mentor for other subs.
As far as the fag/faggot thing in a dynamic, its not something I particularly enjoy. I understand the humiliation aspect of the D/s dynamic, but I feel there are better ways and deeper ways to do it. Those words pull me out of a headspace simply because I don’t connect on any intellectual level with them. The objectification of being a pet/pup is something that in and of itself can (and should) be used to further the headspace rather than pulling in a different direction. I understand that some enjoy it. So the moral of the story here is truly understanding the dynamic that you have and understanding the needs of your sub (or the desires of your Master depending on who you are). As always, communicate. Experiment. You can always sense when headspace is compromised, so be aware of that and use it to strengthen your connection!
