Modesto - your long post ‘above 10# or so .’ is really excellent and I must say that I totally agree with you.
Btw - I found a video about vac hanging where the guy buts a silicon sleeve on his dick, than the dick in the hanger and a second sleeve on top. I think that wrapping as discussed in this thread is much better.
Regarding weight I tried 20 pounds with very tight wrap and it seems to work. However, I want to stick with 15 pounds as long as possible (as long as I see gains).
Later - ttt
