FINALLYYYYY (also bruising questions)

I'm finally meeting a true Dom for the first time!! I'm so excited. Ive been super interested in the D/s lifestyle for so long but I was in a long term relationship(almost 4yrs) with a pretty vanilla guy and since him I've yet to meet anyone that is remotely rough or controlling enough for my tastes. Or they're not true Doms and they're just pricks. I'm feeling pretty confident in my abilities to submit and he seems completely genuine. I filled out an entire long ass checklist and rated each one from NO aaalll the way to 5.

Any tips? Like I said, uber excited.

Now a question I have is- what do you do to hide bruises if you need to?? I want all my pretty marks but I will have times that I probably shouldn't flaunt them lol.
