Does sitting in a tree outside their bedroom window qualify as "meeting" them?
If so, then yes.
Yes, it does. As long as you imagine meeting the person before pleasing yourself while staring at them through the window. At least, that's the angle my lawyer is going for.
Anyway, I dont think it's wrong to meet someone you know from RMM for sex. If you're both consenting adults and you know it's not really going anywhere... then why not meet up and have some fun?
