Yea we had lots of rules at the beginning and to be honest I don't remember most of them. Hell I couldn't remember them when we had them which is why most of them ended up getting broken and most of them have been let go.
We have one over riding rule now, we don't do anything that knowingly hurt anyone else. Also always protected sex, other than that we figure it out as we go.
Safer that way for me anyways as I am the one that always forgets crap.
