As a virgin, I have a sensitive glans, so I cum quickly even when I masturbate. I can cum all the way with girls, but sometimes I explode when I give them a blowjob before penetration... I swallowed my shame and went to visit my mom's sister, who works at a urology clinic. She said, "I have to try to see how fast you are," and she stroked me with a skilled technique I'd never experienced before. She seemed amused that I was still erect even after I'd cum, and she even took my virginity without telling my mom.
