The white things are pearly penile papules.
Hirsuties coronae glandis (also known as "Hirsutoid papillomas," and "Pearly penile papules"[1] ) are small saliences on the ridge of the glans of the male genital organs. It is a harmless anatomical variation with no malignant potential, although it can be mistaken for HPV warts by inexperienced doctors. The papules appear as one or several rows of small, pearly or flesh-colored, smooth, dome-topped bumps situated circumferentially around the corona (see image) or sulcus of the glans penis. They range in size from less than 1 mm to 3 mm.
A similar condition, vestibular papillomatosis of the vulva or Hirsuties papillaris vulvae, occurs in females and similarly can be misinterpreted for HPV infection. Like hirsuties papillaris genitalis, it is a normal variation on human anatomy. http://en.wikipedia.org/wiki/Pearly_penile_papules
