Familiarity eases communication and avoids awkwardness. I think the more you know about someone, the better the experience can be, in my experience. While "new" and "unknown" may have a level of excitement, it also has the potential to be a disappointment.
I really love verbal, and your description of the kind of role play you like is pretty well spot on with my verbal triggers. Making me repeat the verbal humiliation only adds to my excitement too. In addition to that, physical roughness centered on that play only adds to the debasement as there's a bit of nonconsent and objectification to it as well.
I you recall, I popped several capillaries in my eyes doing a certain (ahem) activity with you. I had to make up that I had a severe coughing fit from an allergy attack.
My sessions usually involve a vigorous activity of a certain sort, and I would rather not throw up while doing it. I usually session early afternoon so it's not that bad to go for part of the day without eating.
Pretty much the same deal every time. Shave the usual places, shower, clean myself out (which I do for a while), drink only water, drive in, I usually arrive like 30 minutes early so hang out in the area for a little but until I make the call up.
Only all the time.
One time I remember having nipple clamps with chains on, and was told to crawl over to a certain spot. Well the chain got under me knee and ended up yanking off the clamp, which was a nonoptimal way to get them off. Mistress laughed pretty hard. I think it was funnier for her than for me, but it was pretty funny in the moment.
I've had crushes on a Mistress, but I think that can be a normal emotional response. It hasn't created issues for me, mostly because I know the nature of our interaction, and I'm certain the feeling wasn't mutual. So, its easy to get out of my head.
