Not exactly a personality change. But when i was younger bdsm was a way for me to satisfy a kink or a desire. As i have grown older and more comfortable it has been more of a way to express my feelings and experience a sexual connection with the women in my life. I limit who i play with much more than i used to and i have to have a deep emotional relationship in order to truly enjoy the experience. Ive been lucky that over my career as a sub i have been able to develop that connection with a few people both pro and non pro dommes
