Let us try to keep the tone of this very light-hearted and positive, as opposed to turning it into an angry bitch-fest (you know how we ladies love our bitch-fests :P).I'd like to compile a list of things providers and hobbyists often seem to overlook or forget. I will start with a few, and I would love your input! Extra brownie points for putting it in joke form or providing light-hearted anecdotes.
This is meant to specifically be about things that are very often forgotten by many, so one-time issues that you've come across aren't really applicable. * Brushing your teeth is awesome and certainly appreciated, but PLEASE remember to brush your TONGUE. I had a client recently that wanted to kiss a lot, and I swear it felt like he had kind of a slimy carpet on his tongue! *gag* I wanted to give him my extra Orabrush (get one!) but I'm not sure he would have used it. :P
* That lint that your belly button collects? Not sexy. I'd say one out of three clients forget to check their lint-trap during personal grooming hour. Oh, the sweaters I could knit. :P
* "Can I ask you a personal question?" I always cringe when I hear this. ESPECIALLY with a first-timer. I want to say no, but I almost always say yes, and regret it. What follows is usually something like "What is your real name?" Traci Brooks.
You came to see Traci, let's not get complicated. * Please don't spend 20 minutes trashing your wife to me. Actually, if we must discuss it, I would much rather listen to all the wonderful things about your wife than all the ways that I am better than her. I'm sure this goes for the ladies as well. Don't spend the whole time talking about your current or ex hubby/boyfriend. I'm pretty sure it effectively kills the mood. :P
Please feel free to add your own reminders! Just remember to try to keep it light and neutral, as opposed to aggressive. I'm very curious to see some of your answers.
Where is the tattoo? Please tell me you tagged your butt for me. "Traci wuz here!!" 
LOL.
