I don't allow men to finger me, period. In my experience they have absolutely no idea how to do it and I have no desire to be a mentor in "your fingers curve for a reason" games. Plus I find male hands a lot more rough texture wise than female ones and its something I reserve for my own personal sex life with my female partner(s). On the brief occasion I've let the rule slide, I've became instantly mentally uncomfortable to the point I find myself mildly disassociating from the entire meet, which isn't healthy in the long run for anyone so no-one gets a shot. I don't care if they play around the area externally provided they realise my clitoris isn't a button on a remote control with dying batteries.
Speaking of the American thing, I get totally turned off by British accents (yes, all of the British accents from Orkney to the Isle of Man) saying 'pussy' but oddly its quite erotic in an American accent to me? Conversely an American saying 'cunt' just elicits the same reaction in me as a Brit saying pussy? Odd. I guess some words just sound better in different accents. If someone started developing a faux American accent during sex it would take all my self control not to burst out laughing
There have been clients I've met that have brought out my own natural accent though because they're of a similar cultural background, which can be quite entertaining when after 10 minutes in their company, I sound like a completely different person...
I don't get the slobbers at all. And if they have really bad oral hygiene/care I just can't do it. They can be lovely guys but I feel sick kissing them; I've always had a thing about my mouth and dental care and bad teeth/waterwell saliva mouth just... I'm making myself retch thinking about it
