I (23f) am often feeling to much shame and guilt to bring up my kink to my fiance (25m) he knows what it is and says hes ok with most aspects of it but I refuse to engage in it for fear of him hiding his feelings about it or just thinking its too gross and leaving. I can't even talk about fantasies I have surrounding it or get into the nitty gritty of what turns me on because im too embarrassed.
How do I bring it up? How do I talk about it without shutting down inside and feeling gross about myself?
