Sir_Russell, I appreciate your input, and I hope it's clear that I'm not insulted. I do not take anything you say lightly, as your experience is obvious. I would hate for there to be a legal misunderstanding, and will bring it up with my husband.
There doesn't seem to be much concern in this thread over a few marks, so long as it is occasional and not due to severe torture or anything. I'm quite happy about that, and will take the precautions necessary as well as make sure aftercare is tended to.

Like I said, referring to me as a newbie was probably deserved, so if I seem to be blindly skipping into dangerous territory and anyone notices (I say 'notice' not to be insulting, but because I don't expect anyone but Him to be constantly aware of my status/choices/etc), I am grateful for well-intentioned guidance; I am always willing to learn and grow. Thank you again! I do know time is valuable, and I am very grateful to everyone who devoted some of theirs to my concerns.
