My boyfriend and I are not married, nor do we consider ourselves married or common law even though we have lived together for quite a long time, however he bought me a diamond ring which I wear everyday on my left finger. That doesn't mean I am disrespectful of married people. Not a good analogy I know, but it was all I had.

A collar is not defined by the relationship, you can wear a collar and not have to be a definate D/s couple, because there is no definate term for that.
A D/s relationship is what you would like it to be.

So no you are not disrespecting anyone at all by wearing something your boyfriend bought for you.
I do know that people place quite a bit of emphasis on collars and the wearing of them. That is what they deem important to thier relationship.


If you are comfortable and enjoy wearing your chain that he bought for you, and he is comfortable with the reasons you wear it, then there is really no problem at all with it.
