but watch the videos by the Clone-A-Willy company MULTIPLE times before you try to do this the first time. The molding material hardens VERY quickly [like, if you stir it for more than 15ish seconds, it will start to harden], and if you don’t get your goods in there fast, they may not go in at all. If that happens, the company sells extra molding powder, but you can also find it at craft supplies stores. Consider using a cockring for a harder hard-on, and to help maintain your erection throughout the molding process [this is a great partner activity if you have someone to talk dirty to you while making the mold]. Also, try not to touch the edges of the tube - if you do, it’ll cause part of the mold and final “Willy” to flatten on the side. If you’re a little on the girthy or curved side, there are tips on the website as well, but I would also recommend using a larger tube - a soda bottle could probably work. When you’re pouring the silicone into the mold, be sure to tap the tube to prevent bubbles. TLDR: do your due diligence before you mix the molding powder!
