8 XXX : bdsm

I have a session with a newer sub this evening. She and I haven’t done any position training yet. I just sent her this image and said ‘I wonder how many of these you can memorise before this evening’. She has four and a half hours so let’s see how she does...
What an excellent poster! As a switch I'd best lean how to assume each position as well as send to my man to enhance our fun xx
Out of curiosity, do most partners actually memorize this type of thing? I'm trying to learn how to be a better dom for my gf, she just shared this subreddit with me so I'm trying to learn as much as I can.
My sub knows if she does not remember them I will punish the shit out of her.
