The butt-simulation theory states that v-v sex had an adaptive
advantage, because it favors monogamy (i.e., it's less anonymous
because you can see who you're with).  On this theory, however,
our primate ancestors still routinely engaged in d-v
(dorsal-ventral) sex, like other primates.  The woman's breasts
favored the transition to v-v by making her ventral side more
interesting to men.  This, at least, is what I remember from
Desmond Morris.  I'm not sure I believe it, but that's the
theory.
