Look, assuming this is true, I’ve learned that having a fetish is a very normal thing. Everybody has one, especially those who deny it. So unless your fetish is genuinly harmful to yourself or others, you don’t need to “get rid of them”, that’s very unhealthy. And even if you’re ashamed of one, just masturbate to it in private, but don’t surpress it.
Yes, some fetishes are really weird, but quite frankly the thing about them is that nobody can understand a fetish unless you have it yourself. So that’s why I try never to kinkshame, even if it truly disgusts me. I mean, I have some too (and some I’m more private about than others). And while some are very tame and others less so, they’re probably just as weird to others as theirs are to me. Hell, I’ve even tried to analyze my fetishes so I could reasonably explain the appeal to “normies” (so to speak), and I discovered that it’s not always very easy to do (the analyzing bit, not the talking about it. That’s even worse).
Besides, dragons (I assume like furries)? BDSM? Pet-play? Yeah, I’m no expert but I’m pretty sure those are harmless and/or common. Not need to kinkshame it.
