Rule No. 2: Keep it Sane and Sober
Head out, look for a hot play partner, unpack the doll case and … delay … what number of cups of wine did i've? Warning sign! Stop! All bets are (or must be) off!
You shouldn't, ever be playing, never as negotiating, if there is any type of substance within the mix - liquor, medications (also individual meds may be a challenge in certain circumstances) are typical deal breakers. In an expressed term: Don't get it done! You will have another right some time destination to share the enjoyment. This is absolutely essential to remember and respect in rough play.
This really is a a bit more subtle it matters than it might sound, but. Often we are exhausted, or have actuallyn't had much for eating or haven't gotten sufficient rest.
