It's 100% all natural, requires some very basic maintenance (peel back and and lever 2000 that glans) and best of all, it feels amazing. the foreskin is actually a mucous membrane, and it contains it's own pleasure nerve endings. During sex the foreskin glides on me and my g/f. On the outstroke it prevents contact. I have tried sex while holding my foreskin back and that outstroke feels abrasive. Speaking of abrasive, thank god I my dick closes up when not in use, even my soft blanket hurts a little to rub up against when I wake up with morning wood. I couldn't imagine my dick head vs the scratchy world. Obviously my dick was not meant to have sex with jeans, towels, blankets, or even boxers. To conclude, all this talk about my dick is making me want to go spend some quality alone time with it.
