Some of these products have been tested in real life for penis size, which are:
Voodoo Penis Enhancer This is a new product that came out last year. It's a great supplement to help a woman's G-spot grow larger, and has been tested in a lab. In addition to G-spot stimulation, this product can also help with erectile dysfunction. You can purchase it online here. The product claims to increase G-spot stimulation and enlarge the urethra, but there have been no reports of this actually working. Some doctors have also reported that this product may actually work to create more sperm and lead to an increased risk of conception in the future. To help prevent any negative consequences, you should only buy products that are tested in a lab. Voodoo Penis Gel is another option, and you can see it here. The Voodoo Penis Gel I can't get enough of these products. Even when they are not advertised as being an "erotic enhancement" they are still extremely popular, and people have been getting them for years. These products all promise to be a "delicious mix of penis growth, erectile dysfunction, and increased sexual pleasure" (my review). I've personally had some of these products for about 8 years, and they have had a dramatic effect on my life.
