rach, you know of the dangers so I won't repeat the advice those above have given, except to add...
If he doesn't want a relationship, that's fair enough. But he should be prepared to address your concerns by meeting for the first time in a public place.
I've met a few people from here, and even though I'm the guy, I've taken the precautions myself and/or been aware of the need for such precautions. For instance, I met minx in a public place and made sure we were never totally alone, and I answered any questions sheepy had before she came over to see me.
Oo one final thing, though. Just because you might meet for the first time in a public place and stay in public, that doesn't mean he can't stretch his dom muscle... *winks at minx*
Be safe, be careful, but have fun and good luck.
