From what I can tell, most people have the same fetish all of the time, usually starting in their teens. And I do have one that started in my early teens and still have now (its a situation not an object), but there's other ones that come and go. Sometimes they are linked to the "obsessions" I have, sometimes they aren't. Sometimes they are linked to the main ongoing fetish, sometimes they aren't.
These are more short lived and then go away and then another one starts , but not always straight afterwards. They can last anywhere between two months to two years (roughly). The current one is my current obsession (an object). I started a new obsession about two weeks ago, and after a few days I started to get aroused at the thought of having one.
This object goes very well with the main ongoing fetish too so it's extra exciting. I fantasise about this a lot (both the object and situation together). I really want to buy the object and probably "act out" this fetish, but I don't know. This one doesn't involve anyone else.
This just doesn't seem normal.
