Has anyone ever had a bad experience telling someone?

Thankfully I haven't had it happen personally, but has anyone had a bad experience telling someone about their cardiophilia?

The closest thing for me is telling someone and I can tell they don't quite get it.

Many years ago I confided my cardiophilia to one of my girlfriends. Unfortunately she didn't understand my passion

Never had a true bad experience, but definitely had some times with mediocre responses.

My first girlfriend in high school asked me one time over AOL if I had fantasies about her. I told her I wanted to see her get examined at the doctor's office. She told me that was weird and never came up again. My second girlfriend in high school saw my stethoscope collection in own of my drawers but that didn't go any farther. I remember once or twice trying to ear steth her (more so in an subtle way) but she didn't seem very keen on letting me do it.

Since then I kept my fetish interests mostly to the online environment. Fortunately I've had play partners that I've engaged in fetish play with.

Yes, something like this happened to me earlier this year. I met someone. They wanted to get into a friends with benefits situation with me. Things went smooth, so I figured I'd tell them about my fetish. What I got was a stare of disapproval. This made me feel rejected in a way, because being a cardiophile is part of me and I don't want to supress it. We called things off rather quick, which was for the best on both sides. But man, this hurt a little bit.
