During the act of unprotected coitus
, immediately post ejaculation the male holds his partner is a pseudo-snuggle until the sensation of impending urination strikes. While the penis remains inside the vagina
the male relieves himself, allowing his urine stream to flow freely, flushing out any seminal deposit and filling the body cavity with urine
Note: When the flush'n'fill leads to a aggressive yeast infection, it is called the sourdough croissant
Don't worry about getting knocked up, I gave you a flush'n'fill, though you might smell like a pickle jar now. Warn me if you develop a sourdough croissant.
