1) Get a trac-fone, google-voice or similar app. NEVER use your real phone number.
2) If an escort requires personal info (name, work) to screen you, don't see her. It's her loss, not yours. Never have a girl come to your actual residence.
3) Google the escort's phone number and tineye.com/google image search her photos. Most ads use fake photos. Some girls will still look good, others not so much.
4) Always call the first time. You can tell a lot from her voice. Be friendly and professional on the phone. Ask only: are you available, your rates by time, do you have incall/outcall. NEVER discuss sex over the phone.
5) Leave behind everything other than the exact cash you plan to spend and your car key. Don't bring your phone, wallet, watch, house keys, jewelry, business cards, id. Leave it all in your car.
6) When she opens the door, walk in, make sure she's alone, see if anyone is in the bathroom (other girls in there is ok), if all clear, immediately place the cash on the dresser.
7) NEVER discuss sex for money. She will get naked on her own. She will start a bj on her own. You never discuss what the money is for.
8) When the fun is over, get dressed and leave once your time is up. Don't loiter. If you pay upfront you don't need to tip.
If you follow these simple tips, you'll have a majority of decent times in the hobby.
