My 3 cents worth.

Don't want to re-hash over what has already been said. All great and valid points from obviously very experienced technicians in their respective fields

You might want to consider filling out a BDSM check list, if your Dom is getting you to do things you do not want to do, then this has to be known to both of you. The checklist is a sure fire way of decreasing the communication breakdown. Especially if are required to do tasks over a long distance relationship.
