Personally i see PSE as more of an attitude than any particular sexual act. Ladies that I considered PSE were very energetic, vocal and in-the-moment. They enjoyed it all as much as me. Talking is constant, there's a lot of communication about what to do, how great it feels and what to do next; in very explicit, dirty terms. Lots of encouragement both ways too. Basically if I feel like I'm in a porn flic then it's PSE
The most PSE woman I've ever been with just had constant orgasms, she could cum from nipple play, DATO, greek, and in any sexual position. And I could feel her cumming, and oh man was she loud. It was all a HUGE turnon, all the senses were involved in the experience
