Yes, I agree that there are rules that I have called "obvious" such as no sexual contact, no exploitation, no dual relationships, no reciprocation that is misleading, no flagrant exceptions (like not charging), and all those things that make the relationship a therapeutic one and not a regular one. I just take that for granted that these things are in place and clear. It is more the subtle things that I was trying to address. And also to find out why people feel so strongly when the issue comes up. I have learned some reasons why now so I have taken in opinions that differ from mine and will consider them further.
