Normally, the penis wants to travel upwards, but gravity pulls it down to a more or less horizontal position. Depending on the size, upward pull and mass of the penis, this is what causes some people to have a more upward pointing erection. In space this does not work as intended, and the astronaut with the erection will end up uncontrollably doing back flips for the duration of his (or her) erection.
