they don't usually act wayward adn pursue sex... strange...
I'm sure it's rare,but I do remember a couple of times where sex continued. My first thought would be that "she" isn't who he's thinking about during sex. That might account to why he doesn't want to kiss during ML nor act very interested.....plus he quickly reminds her that it meant nothing, and was just sex.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
