I have never really heard about that. I know that different types of suicidal thoughts mean different things.

The only thing I can think of, and it's purely a guess, is that if you injure "private" area that might mean past abuse...something along that line?

I know I injured my "chest" in the past to try to turn men off...didn't work. I've also hurt other areas because of guilt. Maybe it's something like that?
