Does Vayikra 15:16-18 mean men must always wash their whole bodies after any emission of semen and couples must both wash after marital relations? When must they do it? eg immediately after? before the end of the day?
'16 And if any man's seed of copulation go out from him, then he shall wash all his flesh in water, and be unclean until the even. 17 And every garment, and every skin, whereon is the seed of copulation, shall be washed with water, and be unclean until the even. 18 The woman also with whom man shall lie with seed of copulation, they shall both bathe themselves in water, and be unclean until the even.'
