My penis is about 1.5" flacid and I can easily push it in flat with my pubic bone without pain (thus the trapped or hidden penis conclusion). When erect, it gets up to about 5.0 to 5.5 inches. When erect and I'm standing up, I can push it down and point it directly to the floor without pain. If you can imagine a straw and bending it in half, that is how it feels to me. When erect, I can feel down the shaft and just about where it goes into the pubic bone is where the "crack" or break is located. While erect, I can feel the shaft going all of the way down to my anus. If I measured from the tip to the point at which I feel it stop near my anus, it would be about 9 to 10 inches.
Also, my scrotum may be providing a slight webbing to the shaft. Based on my description, is it possible to have an operation and release the penis such that flacid it is longer and when erect, the full 9-10" is seen? I'm in my early 30's and 6'8" tall so having a small penis really looks strange on such a large body. It's been like this as far as I can remember. I remember as a kid have a severe bicycle wreck hitting a telephone pole and my crotch was slammed against the handle bars. I remember my crotch being sore for days. This was at about 8 years of age and maybe this is when the break occured. I have been too embarrased to go see a urologist; howevere, for my company physical, the doctor made no mention of the small guy.
