Piano, I hear ya about the barn analogy....but I think I might also not always be injecting with a 90 degree angle. With an improper angle, I could be injecting semi-sideways, which might explain why I am not reaching the cavernosa sometimes. If I am on the "edge" of the cylinder and not taking a proper angle, I could miss the cavernosa because I am injecting down the side of the cylinder instead of toward the middle of the circle, so to speak.
I can tell when I hit the mark properly because the plunger depresses easily. My automatic injector automatically injects, but I still have to depress the plunger...and when I hit the mark well, I get a definite, desired effect ...although not yet as firm as I strive for...lol.
Thanks to all for your tips.
