Are you Christian or have you ever been Christian? I was raised baptist.  It's common in baptist communities for people not to have friends of the opposite sex.  I bring it up because you mentioned men.  From religious folks I've also heard this s lot from women.  Liberals make fun of Mike Pence but he's an extreme example of this phenomenon in the way he speaks about it.  But the sentiment is common among born again Christians.
