Love to hear from more guys who do this.
Like George and Kris related in their experiences, I too love to rub my penis on the bed or a pillow.
I started masturbating when I was about seven by lying in bed and rubbing my penis aginst the sheets. I would do it till I got the 'tickle feeling' which is what I called my dry orgasm.
Sometimes it excited me to take a pair of my Dad's briefs and rub on them. I didn't always rub naked, most times I would do it with my underpants on. To this day my favorite way to masturbate is to hump the bed with my underpants on.
I'd love to hear more stories from guys who masturbate this way.
