So if you are actually talking about reducing the anterior (?) width of the pubic bone, it seems like that would mostly increase the useable length of the penis, since it’s the pubic bone that women hit when they’re grinding down hard on my throbbing cock — pounding again, and again, and again as I massage her beautiful breasts and thrust upward to meet her…
Okay, back now. The point is, “shaving” the pubic bone wouldn’t actually lengthen the penis; it would reduce the “height” of the abdomen. I don’t think it would reduce it much. The bone itself can’t be more than an inch or so across at that point, and I don’t think it’s a part of the body that you want to weaken by rendering it thinner.
