The TOW Stretch Help

When Doing The Tow stretch how do I perform it without stretching the skin on my dick? How do I go about it without only stretching the skin and not the ligaments? any1 got picks of how to do this properly

Firstly, you will get skin stretch.
Secondly it isnt a ligament stretch, its attacks the external [outside] of the tunicae [penis] and this is all EXPLAINED in the TOW thread I made, goto the top of this section into the exercise thread, where everything is listed and find the TOW stretch.
Also PM TennisNut, he has ALOT of expertise with this stretch and it works good too, dont be fooled for one second its a skin stretcher.
