It can get messy, especially if someone is trying to be artistic about it. Also, it requires sitting still for a little bit, "doing nothing." So, yeah, I don't think you'd enjoy it.
I can't think of any LSEs that I know who would enjoy an herbal bath or even do one unless it was medically necessary/advised or if their SO was in there, too, in which case I don't think it would be exactly relaxing. Doesn't mean it couldn't happen, just that it doesn't fit what I already know.
Oh, to find you in dreams - mixing prior, analog, and never-beens... facts slip and turn and change with little lucidity. except the strong, permeating reality of emotion.
