Is it bad to have many masters? I love the feeling of being wanted. If I did decide to stick with one master for now, what should I be looking for?
A more serious reply:
You don't need to have many masters to feel wanted, a master who doesn't mind (or rather enjoys) to put you in situations where you can feel wanted is the (simple) solution. So you should avoid the possessive, jealous type and go for a more self-confident one, one who allows you to fool around with others.
