Foreskin piercing is not for everyone, but many uncut men have their foreskins pierced, usually on the underneath of the foreskin, but there can are many variations to where the piercing(s) can be placed. Rings can be attached, then pulled on, stretched and hooked onto other rings or surfaces. It is always advised to use caution especially when dealing with sensitive skin like the foreskin when engaging in S & M activities. Tearing the foreskin is serious and not something that’s to be taken lightly.  

Foreskins vary infinitely from very short to very long, from very loose to very tight. It is up to individuals to experiment with their own penises and those of others to discover and treasure the joys and pleasures that this amazing structure entitles. The more men find out what is actually possible with their foreskins, the more valuable the information which can then be passed on to others. In this way there will no longer be any ignorance from the deliberate misinformation and misguidance, which has been perpetuated by those institutions in society that have abused their powers of authority and promoted sex taboo.
