It has been a long time since I was on a BDSM forum, and as I read, something occured to me. (omg! a thought! -marks it on the calendar-)
anyways, the terms for a dominant are very gender oriented. There are Doms and Dommes, Masters and Mistresses, and Sir's and Ma'ams.
Yet submissives... we all share the same terms. Slaves are just slaves. Pets are just pets. Sluts can even be both. Yes, some submissive terms are only one sex, such as 'cunt' but this is not to differentiate gender, but this is more because they are anatomy case. (I haven't met a male who has a cunt...)
So I think we should be called sub/bes from now on. hehe. It would make my life easier anyways, I always worry about calling someone by the wrong gender if they have a gender neutral name and haven't said anything to distinguish it.
