Why is seeing others having sex arousing? Is there some sort of evolutionary basis behind it? (NSFW)
Yes. Group sex does different things for each gender. Group sex for males means they have a chance to pass their genes along when they otherwise wouldn't.
The Short Answer
Yes. Group sex does different things for each gender. Group sex for males means they have a chance to pass their genes along when they otherwise wouldn't. For females it means their off-spring won't get killed. If an offspring isn't a males, then that male is likely to kill the offspring allowing more time for a female to raise *his* offspring. With group sex, nobody is sure whose offspring is whose, so we can't take the chance of kill babies that might be our own. Now, I should clarify these behaviors have been observed in certain primates which we are closely related to.
