My perineum is one of my favorite parts of my body. I frequently include it when I masturbate, and a couple of mornings ago it helped me out again.
I was using the position I developed when I was a kid: lying on my stomach with my scrotum in one hand and my shaft along my wrist. The orgasm I was chasing was proving to be a bit elusive, so I thought just a little more stimulation might do the trick. So with the middle fingertips of the hand I had my balls in I started short little pushes on my perineum and within seconds I was there.
I love that little spot!
