DrSkipper, I'm so sorry this happened. If you see or can see a therapist, that might help in getting past this event. Give yourself time.

Meeting with someone offline, whether or not kink is involved, is a risky thing. There are a number of kink websites with safety tips for online & real-world interaction. Here is one:
BDSM -- Some Notes on Safety for Meeting On-line and Off

I hope you find some useful information.

And if you meet with anyone who begins to engage in kinky play without a lot of negotiation of the scene & talking about limits FIRST, run, don't walk away.
