Talking of stirrings on the trouser dept....
Has anyone had the experience of some ( very transient) penile fullness on defaecating? I had it once, maybe twice, there, but so short lived to think I had imagined seeing it. In no way am I thinking this means erectile recovery- it's just that we are told that surgery has caused trauma to the nerves and blood vessels responsible for erection, so it was unexpected- but it got me wondering where it came from.
OK, I get the trauma thing. So that is one reason for the use of a vacuum pump- to draw blood into the penis and temporarily trap it there. An understandable way to get round the issue. Some external mechanical force is used to change blood flow- and doing it in a very crude way- but it's the best available- or is it? More of this later.
Back to my original observation- I'd guess I'm not alone in that, pre -surgery, occasionally , when 'taking a dump' ( defaecating), an erection would spontaneously occur. Presumably because the pressure in the rectum pressed against the prostate and associated structures causing a pleasurable sensation, or maybe the pressure just altered the venous leakage from the penis. Anyhow, the result could have been a stiffy. I'm not aware of any penile rehab measures that harness this phenomenon.
Now I understand that it's not a good idea after surgery to shove things up your bum, or to strain- there's the risk of all sorts of trauma- rectocele, damaging the anastomosis etc, but it does serve to highlight the fact that direct stimulation of the external member is only using a small portion of the sensory area available - and this might have implications for rehab...Is anyone prepared to climb the wall of prudery to discuss this?
Anyhow, back to vacuum pumps. I'm yet to get to that stage where I could try one out- but once again, I like to try and reason out why and how things work. Why do none of the vacuum devices have a stroke facility, i.e akin to the action of masturbation?
From a rehab point of view, surely this would be far more beneficial than merely sucking blood in and tourniqetting it. Whilst this technique may expand the corpus cavernosum and allows the possible resumption of some sexual activity, it sounds as if the period inside the pump is spent in an entirely passive manner.. There does not seem to be a facility with vacuum pumps to provide sensory stimulus via a simple up/down stroke whilst in the vacuum. All the action takes place after vacuum assistance- i.e. at a time of relative disadvantage. I noticed that there were sex toys of poor quality that had this combined vacuum pump/ stroke facility- so it would seem it is do-able. Maybe it doesn't get translated into a useable rehab device for reasons which I am ignorant of- or maybe it's just a mix of cost and complacency..
