I have been lurking around this forum for the last month or so and I thought I might jump in to answer some of your questions as I have been using the Andro Medical Penis Extender for the last 5 months, 5 days on, 2 days off. I have gained about 2 cm in length & about 3mm in girth using this device.
For the first 2 months or so I was wearing it for 7 - 8 hours a day, taking the device off every 2 hours & massang the glans to encourage blood flow back to the glans. During this period I used to feel a really good stretch at the base, so I think it was working on the ligs. The last 3 months or so I only wear it for about 3 or 4 hours a day & I find that I can feel the stretch along the shaft of the penis. I wear the device facing upwards towards my chin, so I guess it’s working on the tunicae after reading BIB’s LOT theory. But what doesn’t make sense to me is that according to BIB’s LOT theory if you stretch downwards you stretch your ligs…well I have never stretched or worn the device downwards and my LOT is around 7pm…
