I'm a virgin and my glans is too sensitive or I masturbate and it shoots right away. I can cum to a good point with a girl, but sometimes I explode during a blowjob before insertion.... I went to my mother's sister, who works at a urologist, and she told me that I needed to see how fast I could cum, so she gave me a blowjob with a technique that I had never experienced before.
