[paradigm]

one organ develops outwards and has a dispatch terminal.. the other develops inwards and has an inward goods terminal (grin).. a penis can still deliver semen without orgasm (albeit not so quick and voluminous), just as a uterus can also deliver an egg without an orgasm.. maybe the orgasm is the big bang of procreation, but if we're going to talk evolution, organisms tend to develop a thing before it finds a use for it.. take the development of the eye, originally starting out as a light sensitive cell, and eventually providing survival of that species.. i very much doubt that the orgasm was developed for a delivery system, but rather helped deliver survival for species that have it.. chicken and egg, i rather think the orgasm came (pun not intended) first, and not gender specific, and survived because both parties need to want it.. (testosterone charged males aside of course)

edit: do jelly fishes have orgasms?
