Topping from the bottom is where a sub manupulates the Dom in some way to ensure that they get what they want. It is an activity which is generally frowned upon as it indicates that the sub is not really being submissive but is in fact telling the Dom what to do. There are a variety of degrees of this ranging from subtle emotional blackmail to the more blatant 'here is a list of things I want you to do to me and this is what you wear when you do it'. The former is common in many relationships and in some cases may not actually be Topping from the bottom (or at least the participants may not realise it is or think that they are being properly submissive). The latter is common in male 'subs' who visit Pro Dommes where in many cases they try to give the Domme a complete script to follow.

Not seen secretary but I agree with Oz that is is clearly a step in the right direction. Though I don't think Holywood will ever depict BDSM in a normal, realistic manner. They need the drama and the emotion and they will never get that from a normal woman who decides to be a slave without the abusive past ands without the emotional trauma of the transition...
