The term slave it just that a term... just as submissive is no more then a term.

i know "subs" who are actually slaves (from my perspective) and "slaves" who make me question at times if they are even subs because of how much freedom (one again from my perspective) they are given. The term that fits best for your relationship is what is important, nothing more. Just as the rules established by your relationship is what is important.

i do need to say that "slaves" do not become inanimate objects, give up much of their individuality, and their independent thought or have their entire worth is dependent on their Dom(me). That may be the "impression" that is given but 99.9% of the "slaves" i know still have themselves and make the choice, in all things, to follow the lead of their Dominate. i personally think that makes them understand their entire worth more so. Because of the training, dedication and commitment needed to give that type of free service. And yes, i am a firm believe that even a slave is giving their services freely... if they didn't want to be a slave for that Dom/me, they wouldn't be there.

The slave/sub debate is an old one and as everyone knows just a matter of definition which needs to be worked out in advance with one's Dominate.

As to the collar... it is a symbol. Just like a wedding ring and means a higher level of commitment, trust, etc. But, once again, it is what each couple views the symbol. i know some who believe in velcro collars, which can be easily removed when the next "more interesting" person comes along and some who believe in the permanent collar, that will never be removed. It is what works for each person/couple in a relationship, as long as no one is hurt unnecessarily, etc. and enters the relationship with a full understanding of what the collar means.

Just my 2 cents worth.
