Hello, I have discovered/invented a penis enlargement "technique" and "device" combination that I have not seen or heard of on the internet or anywhere else despite a lot of research. I have been experimenting for about three years and have gained a full 1.5 inches when flaccid and erect. While in use on me, after the three years of experimenting, I measure 7 7/8 inches and it can be worn for hours. The advantage of this Technique-device combination is it can be used very effectively during sex with all the advantages of the extra length or worn under clothing with all the advantages of the extra length showing. In effect, this device-technique renders Viagra and Cialis unnecessary. This is not a drug or rubber add-on. Penis length while in use is measured dorsally from the pubic bone to the tip of the penis. I want to share what I have learned but I also want to make some money. I can take pictures and videos that would not give much away except proof that it works. The device portion can be built for $10.00 or less. However, I want to charge a fee to teach how to use the device. How can I do this on the internet without giving it away or having it stolen? Thanks, Crotalus
