1. Get to know the Master before you meet Him
2. Trust your instincts! You have been interacting with people for years, listen to that experience.
3. Check out their references. Talk to people they've met before, find out things that they haven't/won't tell you.
4. Meet first in a public place. Don't be afraid to limit the first meeting to be entirely in that public area. Let someone you trust know who you're with, and where you are, and when you expect to be home. Trust them to call the police if you don't return on time. Call them if plans change!
5. Don't let them push you into meeting or scening with them before you are ready to do so. If they insist consistently, leave the relationship.
6. Agree on a safeword(s)
7. Do not rush into things
8. If spending time alone with the Master, arrange a check in phone call with a friend. Use code phrases to say "Everything is fine" or "Help, get me out of here".
