i've never been to a Mikvah. i've never even seen one upclose, just in photos. i'm not sure how i'd feel about going in one, because i'd be a little sketched out by the fact that there's another person in there just sitting and watching all the naked people entering the Mikvah. but i'd at least like to actually see one upclose. my local Chabad house organized a tour of a Mikvah in Crown Heights a few months ago, but i unfortunately missed it because i was away that weekend.
