Is this for real?
"Making Love and Sleeping with a woman are two separate
passions, not merely different but opposite. love does not
make itself in the desire for copulation, a desire that
extends to an infinite number of women, but in the desire
for the shared sleep, a desire limited to one woman." from
the book "The Unbearable Lightness of Being

that shared sleep limited to one woman i think is
definitely the best explanation why men always stick to one,
their wife, while on the blind side, looking to have sex
with another woman..they always wanted to satisfy their
desire and that animal instict..this kind of guy might be
suffering a 1month syndrome..having sex with one woman to
another is like changing clothes in a depatment store's
fitting room..
