Do you experience any curvature Blackjack80 or others using the lying on stomach technique?
I started doing it with my hand around age 14 so until then i did it on my stomach.
Would both you guys say you'd been doing it like that for 5 or even 10 years then? I've had curvature when erect for quite a while and I think it's because of this masturbation technique which started in early childhood.
I have been masturbating like that since early childhood and i am too quite short. around 5"
How long have you been masturbating like that for ? I also used that technique for many years but don't think it affects size.
