At a כלי מקוה one dip is enough, although some have the מנהג to dip in 3 times. At a mens מקוה there seems to be many customs. Is one dip there sufficient? Seems not. Most people dip at least 3 times, many dip 6 or 7 times and a lot just go up and down an indeterminate number of times.
So what's the הלכה? Is. there an ענין to dip as many times as possible? Is 12 really better than 3? What does it make you - more טהור? And what do the ones - I'm sure you've seen them - that go up and down like rockets causing tsunami-like waves to a crash into me or whoever else is unfortunate enough to be there, what do they achieve?
So is there any etiquette or מנהג or does anything go. Where can I find it brought down? Which ספרים discuss it?
