well im sure i heard somewhere that it helps somehow by dipping or tilting your cervix or something.
it definately helps me want to BD when im not in the mood.
i dont know if the timing of the orgasm matters too much considering how long sperm hang around for (and this is really interesting) and that the muscles that react in a woman during orgasm can keep contracting for half an hour after (but you dont actually notice it)

well thats my opinion.
