Hi I am Ian. Six weeks post robotic surgery which was painless and had a curative outcome. Regarding vaccum pump types ,I am new to the site but not have seen anyone writing about the bathmate pump. I tried the bathmate hydramax prior to my operation to increase blood flow etc. but found it too powerful ,it felt that it was going to pull my penis clean off. I now have a lower powered version called the Hercules which is ideal and gives me a good erection and has the advantage that there is no rubber gripping the base of the penis as it is filled with water prior to use and sucks on the whole penis. The cheapest I found was on the Love Your Toy site. Hope this info is of some use.
