ADS Question

For an ADS could I just pull my penis down to the desired stretch and then just tape it to my leg?

Ads just like hanging or stretching relies on elongating the deeper structures of your dick - not the skin. So if you want to try taping it might be a little tricky to transfer the pull to the deeper structures. If you only pull your skin you will end up with excess skin. Good luck. (Personally, I think that lead weights or a vacuum hanger are better suited for ads but I am interested in your experience).
