I was in previously in a D/s relationship as the sub about 2 years ago for quite some time. I'm naturally a very passive person anyway so it was fairly easy for me to be trained into it, and after it ended I maintained that sort of "please everyone" attitude. Well I recently met a guy who wants to be dominated by a female and, having had experience with a master, I thought it would be fairly easy to assume the role of mistress. But I find myself having difficulty being the dominant one. I am constantly afraid of hurting him even though he says it's ok and we do have a safe word. I find myself asking him constantly if he's ok with me doing such and such and what would he like for me to do to my slave. I know it's definitely not what a good mistress does to constantly be asking him what he wants instead of being dominant and doing whatever. I want to cry every time I slap him or hit him even though I know that he likes it. I need help being a better Domme because I know I kind of suck at it and I don't want to keep disappointing him (he never says I do but I can tell). Anyone have any advice on how I can get over feeling so bad about it and to learn to be more aggressive?
