Are fetishes genuine or made up nowadays?

I have a bondage fetish lol I love being tied up really tight so I can't move a muscle. I've always been like that too, even before I didn't know what fetishes were lol. Once I got older and watched bondage videos I discovered bondage tickling, I'm super ticklish too so it works perfect for me hehe I love being tickled so much when I can't fight it!
Also have a thing for women wearing overalls, and I like wearing them too sometimes while doing bondage play lol. Sorry to write a book, that's all my fetishes haha
