I saw one provider years ago who remembered all the little things I told him during pillow talk and he would ask me about stuff when I saw him next, it made me feel really good, like he was putting in effort to interact with me personally. He turned out to be kind of crazy though, so no more visits.
Rod Hagen was one of my first experiences like 10 years ago and he was just so friendly and outgoing, it really put me at ease and let me have a great time. I remember him after all these years.
