In JackinQ&A, a guy had concerns about bumps at the bottom of the penis head. I had the same question and concerns all of my life – until recently, when I came across an explanation in the book Dick: A User's Guide. These bumps are called "pearly penile papules." They're considered a normal physiological variant among males, so they're nothing to worry about – just another of the many anatomical variations that makes each of us a unique individual. If you search for "pearly penile papules" on the Net, you'll find pictures and some excellent articles to put your mind at ease. I just don't want other guys to go all their life wondering if something was "wrong" with them.
