My urologist believes I need to start using 1/2 inch needles. He believes that is the primary reason I sometimes do not reach the cavernosa area. He reached this conclusion after watching me inject myself with a 5/16 inch needle.
I see no anatomical reason that I need to insert the entire 1/2 inch, and am wondering if any of you use the 1/2 inch length but do not insert it 100 per cent of the way. If so, is there a trick to stopping short that you could share? If not, I guess I will just use trial and error and see if I can develop a "feel" for it.
