If she has ever been around the lifestyle (involved, know someone etc) then dont say anything further than you have.
You told her enough for her to decide if its a dealbreaker and she hasn't left yet.
If she's never been around the scene then it kinda doesn't matter. There is no real concept of what the life was/is other than non/fictionalized accounts in various media and PSA's which all vastly range from how bad to how awesome it can/could be. Without going into gory details and having no frame of reference it may as well be kaballah or some shit.
