and I can only use myself to measure. I'm just thinking of how I would feel if my girlfriend/slave had another Master on-line. I wouldn't accept it one bit. It's not a matter of jelousy but time. Both of us are busy people and if she would prioritise someone else over me romantically then we would see so little of each-other that we might as well break up.
I'd be the last person to judge anybody. If it works for you then great.
