I agree, I want to be someones 'only one', however sometimes we can't have what we want. I only worry that another sub would know about me too, rather than me just know about her. Like someone said above, you have to respect other people and as long as all parties are happy with the situation then I would be too. But I hate the idea of another sub being made unhappy because her Master had chosen to collar me and not told her. Having said that - in private I am a jealous person, who cant bear the thought of my Master wanting anyone else in the way he says he wants me, but I keep a lid on negative emotions like jealousy and at the moment its working for me.
