Zip Problems

So recently after shredding with the fellas in perisher (russ henshaw, bobby brown etc) i noticed a new kind of style and that was how to wear you pants. i noticed that there has been a major incline in the wearing of suspenders, so driving home after a gnarly sesh thinking about the new dub i just learnt i was thinking of purchasing some suspenders. I heard that russ n the bois all use this brand called tree for lifestyles (bit weird seeing as they don't live in a tree for) I started looking for that brand so one thing lead to another and i find myself purchasing some! when i got home i couldn't help my self so I attached them to my pants, thinking that i was sick and still had the adrenaline in my body from my first dub I went down to my trampoline. so i get there with my suspenders done up and I noticed one little detail, this one really mad skier had his zipper undone with his suspenders so as you do i did it. during my tramp sesh just after i landed a dub 10 i realised a really strong and sharp pain around my penis. I looked down in shock and and realised that my zipper had gotten caught in the foreskin of my dick!!! does anyone have any tips of how to get the skin out!!!!
