Right here!! It didn't start until 6 years ago. I started to deny myself short orgasms and started teasing and denying myself longer and longer. My first happened after 3 days of teasing. The first multi almost seemed like one long one, but it was 2 back to back. Since then multi orgasms are regular and I now have full body orgasms which at times make me 'roar' because it feels like the head of my cock is going to explode just before I start Rocket Manning all over. I actually owe all this to an ex who dominated and pegged me. Once she taught me the pleasures of denial until my partner was satisfied I have had the best orgasms yet.
