Both paries need to protect themselves when meeting for the first time. I use set calls to friends at set times and set code words. I give my license number and anything else she needs to feel safe. I have had subs come across the country to be with me and each time I commanded her to set up her safe calls and times. Each experience worked well for us.

I also had my calls set too, even though we think it is the sub that is at risk I know of a few times the Dom got an unpleasant surprise.
