Ever feel bad / guilty about your fantasies?

Nope- all of my fantasies are inherently demanding consensual/non-abusive scenes and I am squicked cold by nonconsent.

Idly daydreaming on some special lady fistfucking me bowlegged for example. Because SHE is wanting to do it to me for HER pleasure equal to mine.

For a long, long time I was ashamed of my fetishes - sickened even (particularly by the resus-aspects of my fantasies, which I know don't really feature here - too niche even for Zity!). My intense cardiophilia does include darker aspects - so similar to the things you mentioned. Hearts struggling to beat, beating erratically, etc.

I didn't realise until a couple of years ago that there are others who share the same interests, and I honestly can't explain how much of a release that was - life-changing is not an exaggeration. Now I don't feel guilty about my fetishes at all, and I have learnt to embrace and explore them (at least in an online capacity).

However, this online liberation brings with it a whole different set of guilt - I'm an active member of this whole cardio/resus community and yet my partner knows zilch about it. I chat with people about such sexual erotic topics, and post a few cardio-selfies - all completely behind his back. Telling him isn't an option. Giving up this online channel to vent all my secret desires isn't an option. So carrying the guilt is the price I have to pay, unfortunately.

But in terms of your fetishes, whatever they are, if you're not hurting anyone else and can differentiate between fantasy and real-life then I don't think you should feel guilty at all.

I feel more protective of my fetishes than anything else, but not necessarily guilty.

I think the guilt/shame passes the more one explores and demystifies the thoughts and feelings around the fetish. Thoughts are just thoughts. They aren't hurting anyone. I think the more we know who we are and what we would or would not do (actions, not thoughts!), the more we can just enjoy how weird and strange our minds are and share that (safely! consensually!) with others who are like-minded.

I used to have a lot of shame around my fantasies and fetishes but it has subsided over time as I have found that I am not alone.

I don't think one should ever feel guilty about their fetishes. I celebrate the human body and sexuality as well as the individuality of our physical forms. No two hearts beat alike and all hearts react differently to various stimuli. It all has to do with how unique we all are on a physical and ultimately spiritual level.

IT'S A FANTASY!

It's something molecules make in your brain.

Why should anybody feel guilty about a fantasy?

No, not at all. They are fantasies, not real-life.

Maybe a bit. Only because my doctor is a super nice guy and it’s a bit weird.

Sometimes I feel guilty for NOT living out some of my fantasies!! 😄

My massive fetish is buttock injections. Far from feeling guilty about it, I sometimes go to a medical dominatrix who gives them to me in the humiliating way I so feared throughout my childhood and early adolescence - pants down across her receptionist's lap.

More like: I felt uncomfortable, I thought I would not find a woman accepting them.

I have lots of fantasies. Medical exams, enemas, spanking, school paddlings, judicial canings... long list. I do not feel guilty at all. I do feel like it interferes with the rest of my life to a degree due to the amount mental capital I spend thinking about those things. But, guilty, no.

I have, in the past, had guilty or shameful feelings about my heart/auscultation fetish. However, after finding groups like Zity and others, I have come to the realization there are others much like me. With that said, my guilt has faded somewhat.

If someone feels bad or guilty about their fantasies then maybe they need to think about something else. Unless the fantasy is illegal or will do harm to another person.

Raise your glass and let's all enjoy our thoughts.

I can relate to feeling conflicted about some aspects of my fetishes.

I like to watch videos sometimes of larger patients being examined, especially cardiac and abdominal exams. I find it arousing to see a large belly get poked and prodded and listened to. Seeing it squish as the doctor's hands press through the fat and try to feel what's beneath. Just watching videos of overweight people play with their bellies, or having a partner play with it, can be arousing too. (Not people who are extremely overweight -- there are limits -- but definitely people carrying too many extra pounds.) I imagine what it would be like to explore a body like that, to feel its softness. I feel like part of what's arousing somehow is that the weight is unnecessary and unhealthy.

But, health and wellness are important to me, and I wouldn't want a partner who doesn't take good care of their health. I don't mean this in a shallow aesthetic sense, and I don't want to start a "health at any size" debate...but if I'm in love with someone, that means wanting the best for them, which means I want them to be healthy. So I feel weird getting off on something that I would not actually want in a partner.

That's a little different from what the OP described, but I suspect it's a similar weird and slightly dirty feeling.
