David – I’m not sure what additional insights I might have or suggest. I wish there was a single reference for all things ‘post prostate surgery’, but it takes many searches to find meaningful information. When using a vacuum therapy systems, you must be sure to have the penis engorged (erect, if you can get there) for a minimum of about 20 minutes. Short of that, you’ll find your dick may lose length….. (speaking of short)… and who wants that??
Aside from the vacuum therapy, use a receiver with the liner and you’ll be in heaven – an awesome sensation. Would love to hear if you end us getting one, and your reaction. Good luck to you
