Very few of mine do, but I've got this one (lovely, sweet, friendly) guy, who- literally as soon as he's aroused- turns into a complete sexual deviant!! (it's funny though) Calls me names, slaps my ass etc, he's got a huge cock and when he's fucking me he shouts, dirty talks, fucks me hard etc, whilst at the same always checking I'm ok & he's not hurting me etc (with the huge cock!) He's as lovely as ever again as soon as he's cum

He's really grown on me actually lol!!
I usually encourage it if the guy's into it but judge the level of how far it goes (I.e domination) with the individual punter and how well I know them :/
It wouldn't be my first choice either but I'm not too fussed- you could lay some boundaries from the get-go of what you're prepared to take from the more dominant guys, maybe through email/txt/phone when arranging your booking, or face to face as soon as you feel it coming
