I am trying a make your own extender for 1-2

I am a scientist and I see that most extenders have a simple concept. The main thing is safety. So I came up with a simple idea of using foam insulation tube as an extender. The foam tubes (black, used over hot water pipes) are available in Home Depot, 10 feet for under $7. There are two sizes and you can chose what works for you. These are slit and so can be slipped around the penis. You also need to buy tie wraps- Home Depot has One Wrap Velcro ties 5 for $2.70. Buy a set of 1/8” thick O rings that go tightly around the base of the glans (this is needed if the glans ridge is not sharp and high). So, you can guess what to do.

1. Warm up your penis in hot water or wrap for 3 min.
2. Stretch the penis and measure the length from base to the ridge of the glans.
3. Cut the foam tube to the length.
4. Stretch the penis and wrap the tube around below the glans, with the foam tube slit on top so that the tube is between the base and the under the ridge of the glans.
5. Velcro both ends tight so that the tube cannot slip past the glans.
6. If the glans ridge is not sharp and the glans slips back into the tube, stretch the penis further and slip the O ring over the base of the glans . I found that a strip of cloth tied around the base of the glans works even better.
7. With the foam tube slit on top, you can point the penis up under your pants.

Obviously you can cut new tubes as your penis gets longer. So no matter what your size is, this works for any length and for most girth. For really large girth, you may have to go to the craft store and get foam tubes.

The main thing is that this is very safe. No hard parts and you can sleep with this. Also you can trim it to remove any sharp points.

I have used it now for two days for 12 hours and it is nice.. And it cost me couple of dollars only.
