Do I have to have to be still after sex to get pregnant?

-StillWatersRunDeep- Well, based on all the thick tomes I have scoured, the numerous treatises scrutinized and the educational tapes listened to, I have no bloody idea. But--based on some of the movies I've seen through the years, probably not. There's an episode in a book about 1970's hooking in NYC(obviously, before AIDS) where all the girls would jump up and down several times after.I really don't think it matters.
