Anonymity and online dating
Dating services run mail and chat so you can get to know people in a safer and [monitored/controlled] way. Use their platform and the added security it gives.
If and when you do decide to share an e-mail address think about creating a separate and anonymous email address.
Never feel embarrassed to report a problem to the dating service. The safest plan is to meet somewhere public and stay somewhere public. Make your own way there and back and don’t feel pressured to go home with your date. The way people interact online isn’t always the same face-to-face. No matter what the circumstances, sexual activity against your will is a crime.
