All Dommes are different and thus the ways of approach differ as well.
I personally get greatly annoyed when a sub/masochist write to me in a very crawling/submissive manner. A sub should show respect and be polite - but not over the top. When I read phrases such as "your humble servant awaits your every order" or "I live only to serve you", I
know that the person writing to me has one hand typing on the keyboard and one hand jerking off...and I honestly do not find that very charming!
A sub cannot swear to live only to serve me...he hasn't even met me or talked to me before! I want to be approached as a PERSON, not a fantasy or wanking-material.
Also, I want my sub's devotion and submission to be genuine and precious! If he submits to just about every Domme in the nearest vincinity, then there is nothing special and nothing wonderful about his submission to ME! I want to WIN his submission...I want to force him, a proud strong male, to kneel at my feet and look upon me in awe - when we have chosen eachother! NOT before.
How do I want to be approached?
"Dear Diable Angélique....I have read your profile and find it very interesting. Your views on this and that subject are bla bla bla bla....I am a submissive male age this and that living in bla bla bla...I have bla bla experience and would like to bbla bla bla. I would be honored if you would wish to continue this conversation...bla bla bla...mailadress"
In my oppinion this is a very polite letter, approaching me with respect and at the same time treating me as a person and not an idol. Although I do of course prefer a little more information than "bla bla"
It will then be up to be as a person and Domme when and whether I want to establish a more Dominating tone towards this little slave or whether I'm not interested, whereafter I'll send him my thanks for a nice and polite letter as well as my best wishes in the future.
Period...Now that wasn't hard, was it?
