When I got married I was "persuaded" to chuck away all the photographs and other mementoes of my previous relationships. Now I really regret having done so - there are loads and loads of nice memories now lost. That is more or less the same thing you are talking about - the question you asked "How do Masters/Dom's cope with seeing anothers mark on their property" must depend on one person to another - if for any reason you had a new master, it would be up to you to negotiate to keep your tattoo if that's the way you feel about it - I wish I'd negotiated and saved those mementoes - I was a fool.

Lovely to have a discussion with you shy one.
