research shows that sex with a "new" partner is more exciting
than with someone you had sex before, other things being
equal.
of course, if you have sex with a regular partner, it might be more
"comfortable" and "predictable"
so it is up to you what you are looking for... "excitement" or
"comfortable and predictable"?
there is of course also the problem with STD... if you change
partners every few weeks...
