In non-business dealings, I wouldn't care.
Just as I do not want them passing judgement on my past mistakes, and decisions, I wouldn't do it to them. While it works for me, it doesn't work for everyone, but I prefer a "Don't ask. Don't tell". I prefer not to know about such matters. I do not ask about ex boyfriends, hubbys, much less sex acts.
Naive? Probably. But keeps my life from turning into an episode of the O.C..
