Eric, welcome. Almost all doctors would say that the pump is very useful for penile rehabilitation. You had your RRP in July, so it's time to start, in my opinion. I suggest asking your doctor first. The pumps can be gotten without a prescript
ion, and most of them come with a set of rings. I'll leave a link at the bottom for one that is safe, effective , comes with rings, and is used by several of the guys here. There may be a possibility that you will leak urine during use of the pump, but it's plastic and washable, so no big deal. Most likely you won't. A penile pump is valuable for infusing blood into the penis and the general base of the penis area. This helps oxygenate the tissue, stretch the tissue, and fill the cavernous cavities that form the erection, expanding them and keeping them in 'tone'. Most guys will start out with the pump by just inflating and then releasing the pump, letting the penis fill with blood then empty. After a few days, then you can begin to hold the blood in longer, and even add a ring to keep it in for a length of time. Never wear a ring more than 30 minutes. Using a pump and ring for sex is problematic for some, you have an erect penis, but a soft 'hinge' at the base, behind the ring, and it becomes almost like the old 'push a rope' deal.
