I am a regular who has name changed for this as I am so embarrassed.
I am divorced. XH was crap in bed - never made any effort to make me orgasm, just used my body for what he needed.
In 20 years of being together I could count the number of times he made me cum on the fingers of one hand, literally.
I now have a lovely DP and everything in that department is much better 
But there's always a but
I can let DP bring me "off" with fingers, but he wants to go down on me and I can't let him because the one and only time XH did it he said I tasted disgusting and he wouldn't go near that area again.
and I can't believe I just typed that.
Anyway, the thing is, how do I get over this in my head is there anything I can do?
