I agree with what you're saying and I have certainly found that while I may MY standards of a "perfect sub" I also have to consider the attitude/demeanor, experience level of my submissive and type of session which is very important and I will sometimes alter my approach. Also, some clients simply aren't "subby"- this doesn't mean they aren't a great time in session, it just means that power is a bit more equally divided and the session focuses on fun activities rather than behavior modification/molding.
