Need some quick advice

I'm going off the deep end of perv so no need to tell me that. I have some cousins who I found out a few years ago were/are(?) "ladies of the night." The older one was actually caught in the action by my brother in an alleyway years ago. I saw both of their ads on backpage a year or two ago.

The younger one just had a k**, so I won't bother with her. The older one works in a nursing home or something like that now I think. Would I be wrong in bringing up her past or possibly trying to "conduct an interview" about her exploits?
