How to not feel guilty about this interest?

I don't feel guilt over having the fetish, but I do understand what you're driving at. The guilt comes from you knowing that masturbation is sort of waste of time and isnt conducive to living a good, healthy life. What someone once told me and I think it's a good rule of thumb about sexual interests in general is that you have to exercise some self discipline and put it in it's place. Balance your life out, do your best not to masturbate without a modicum of moderation and you'll be happier for it. Otherwise, just like someone who does recreational drinking or drugs in excess, it can consume your life and lead to becoming a full blown dopamine fried coomer.

I used to feel disgusted with myself but I had a fair bit of therapy and now I'm very happy about it and am glad I've got it.  I can't really go through in detail the process of getting from A to B with this because it took years to get there, but one aspect of it, for me, is that it means I never sexually objectify another human being since I want to be the inflatee, and I think that's good for my relationships with people generally.

I wanted to weigh in because being different does not equate to being wrong.  My entire life growing up I thought I was weird for being fascinated by this; honestly, I still think I'm weird but I don't think of it as a bad thing.  The original trigger for me was blueberry inflation but, like pretty much anyone here, I take that fantasy and they superimpose it on an age and gender demographic I find most appealing.  Just because the original source material was a children's story means nothing.  As small children we often have certain imprintable events unfold that we carry with us for the rest of our lives, not usually by our choice, but it stands to reason that it would include children's literature and media.  I don't believe that we can have things imprinted on us as adults the same way we do as children.

No one can make you not feel guilty about this, although I question whether it is actual guilt you are feeling.  Someone mentioned shame, and I'm sure there is confusion and a feeling of isolation because you find something appealing that most everyone normally would not.  Only you can work through those emotions, but nothing you've said is inherently bad or a reason to be ashamed (again, that's for you to work out).  Also, I would like to highlight the difference between having a sexual kink versus having a sexual fetish.  Although the term fetish is used quite frequently, most everyone here has a sexual kink...body/belly/breast/blueberry inflation entices and arouses them, but it is not required for them to develop normal, healthy relationships.  For someone with a fetish, that aspect is necessary for them to achieve sexual gratification, so they are in some ways dependent upon it.  There's nothing wrong with having a kink based in fantasy and some harmless proclivities.  Some people prefer red hair or long legs; others like someone dressed up as a librarian or maybe a doctor.  In some sense, I'm not sure how this fantasy is any different from the thousands of other fantasies and/or preferences other people have.  Just because ours is more obscure and you don't see costumes for it as much (how many slutty nurses or sexy schoolgirl costumes show up on the racks every Halloween?) doesn't make it any less viable a fantasy.  Our demographics are just different.

I felt the same feelings of guilt over liking inflation as a teenager. I felt shame and abnormal and wanted to stop liking it but I couldn't obviously. Then it became more of a weird secret quirk about me I actually really appreciated having. I actually became pretty excited to tell partners about to see their reaction. If they couldn't accept that part of me I figured I was better off without them. Surprsingly no one ever had a bad reaction to it and they always would play up my interest for it even though they didn't share it. 

Everyone has a happy stash of sorts. I see nothing wrong with having one. Just keeping it in moderation definitely helps. I think it also helps to have communities like this where we can openly discuss and enjoy this fetish. Because I would absolutely never bring it up in conversations with just anyone. 

I'm sorry you're struggling, it really sucks having feelings of guilt and shame over something you ultimately cannot control. I went through a similar thought process, maybe I can help.

Remember that shame is the voice in your head telling you that you did something wrong and you should feel bad about it. Do you ever stop to question that shame? Why do you think it is wrong? 

I'm 30 now, I was just a kid when this kink manifested for me (it was Willy Wonka for me as well), and I grew up in fear that I was some deranged monster, but then I found sites like this. Do you know how many people are this site and others like it? A lot. If it's "so abnormal", why do so many people share this interest? 

As for relationships, I was terrified of telling my girlfriend the truth; I thought she'd be grossed out and leave me. But, since we were soon to be married, I decided I had to tell her. And guess what? She was not only relieved, but she found it interesting. No judgement, just honest curiosity. We have a very healthy and fulfilling relationship, and it's only gotten stronger. Plus, she likes to tease me in public sometimes, it's fun to have a little inside secret that no one else knows about.

Please don't try to supress your feelings, that just makes them worse. If you find you still can't beat the guilt and shame, I strongly recommend seeing a therapist/counselor. They can help you navigate these hard feelings and they will not judge you in the process. You deserve to live a happy, guilt-free life. 

In the meantime, you can talk to me whenever you want. I'm no therapist myself, but I do have experience in this particular field. Take a deep breath, try to let these anxious feelings go, and live the life you want to live.

It's good for us all to talk about it, tinja.

Nofap ironically becomes a circle-jerk at some point. Every online community does this, it seems: they become a mini-cult that began around a reasonable idea and then incrementally take it to a greater extreme. In the case of nofap it goes like this:

1. Masturbation should be moderated and controlled
2. Masturbation should be very limited
3. Masturbation should be avoided entirely
4. Masturbation is a serious evil

The people in nofap groups may be genuine addicts, and should avoid indulgence the same way that alcoholics should avoid that first drink altogether because they have poor self control. It's trickier with masturbation because, unlike with substances, it's less clear how much is too much.

The most logical approach I can think of is that indulgence in the inflation fetish should only be curtailed to the extent that it's harmful. This is ancient wisdom from Epicurus:

“No pleasure is a bad thing in itself. But the things that make for pleasure in certain cases entail disturbances many times greater than the pleasures themselves.”

So the question is: Is the thing that makes your pleasure creating significant problems?

Let's use food as an analogy. Every functional person has an appetite for food which is biologically justified the same as their appetite for sex. That is, you get a little reward hit (of dopamine or whatever) in your brain when you consume some calories or reach an orgasm.

In the modern world, we have foods that never existed in nature, like ice cream, which produce more pleasure than healthier foods.

Does this mean you should never have ice cream? No, it just means enjoy a small amount. Don't overdo it.

You know you're having too much ice cream or junk food if you start getting overweight.

We also have access today to artificial means of sexual gratification. So how do you know if you're fapping too much, or indulging in an inflation fetish too much?

I think there are basically two signs of an unhealthy relationship with blueberry women:

1. Spending too much time on it
2. When it accounts for too much of your daily pleasure

Therefore, the signs that you are not overdoing it are:

1. It takes up an insignificant amount of your time
2. Your main pleasures in life are still interpersonal relationships, accomplishment, exercise, wholesome fun, etc.

Lastly, I think a lot of the supposed benefits of nofap are imaginary. It's like people who claim that eliminating seed oils or going ketogenic gave them all sorts of health benefits. It's an almost OCD phenomenon of, "If I just avoid this one thing, everything else in my life will be solved." It's psychosomatic.

TLDR – Nothing too much. Moderate and control indulgence in pleasure and you will be fine.
