I use a pump, but only for therapy. Started with injections about 10 days ago and still experimenting to find the right dose for me. Have not tried sex yet with injections, as I want to make sure the erection is sufficient and that the urine situation, if present, is accounted for, so my wife does not freak out.
So far, two of the three times I injected I did not leak urine. Did not stimulate the penis either, mind you, just injected to see what kind of erection I would get (around 80% at a 0.2ml dose of 30/1 bimix).
The other time I injected I leaked quite a bit of urine. Went to the doctor Friday to ask a series of questions. Copied and pasted below the part of my doc visit summary that deals with this topic:
Leaking urine while erect - Did not have this problem the first two times I used injections, but did have it the most recent time. He said it is not uncommon. Things he suggested to minimize this unpleasant situation:
1. Urinate several minutes before injecting.
2. Significantly reduce fluid intake the last couple of hours before injecting.
3. Try an Actis Venous Flow Controller. The Actis device is an adjustable, reusable ring that can be tightened as much or as little as needed. Designed for men with venous leakage to help them with ED, it also compresses the urethra and therefore does not allow much if any urine to escape. Here is a link to info about using this device - http://www.phoenix5.org/sexaids/other/actis.html - and another link to the website of the company that produces it (see order link in left column of linked page) http://www.vivus.com/main.taf?p=2,2
4. Wear a condom if all else fails.
Bootheel, like you, I am curious about how long this condition lasts. Even if the Actis constriction device works ok, I would rather not have to deal with it long term.
Hope this helps a little bit.
