So my gf and I have had a switch relationship for a while with my being the sub most of the time, how ever when I do dom she has asked me to be more possessive and also initiate as a dom more, just wanna know what are good ways to initiate as a dom that could be a bit possessive in nature? Just stuff to kinda get her in the mood and mindset of me domming that also scratches that possessive itch, a few things she told me was that marks are a big turn on (hickeys) and other things like verbal possession.
