The better and happier medium position, one taken by some dommes, is to specify some expectations for subs on their website or webpage . . .

If you come and see me, I expect you will, sooner or later, submit in these ways . . . One can easily find such statements on the websites of dommes who are highly regarded and favorably reviewed on maxfisch and other reviewing sites. There is no problem with various dommes have sentences on their pages, "You will submit in this way at some point; it may be the first time or the fifth or the tenth; I will make you;" and some subs expect and want that domination!

The approach you are describing by the other domme, without much warning of it, is going to lead to some bad problems and I and others would regard the domme as foolishly dangerous . . .
