Do you mean fetishes, or just kinks? A lot of people use the terms interchangeably but a fetishes specifically refers to something that you need in order to become aroused, while a kink can just refer to an unusual sexual preference. All fetishes are kinks but not all kinks are fetishes. At least, that's my understanding on the matter.
For example, if you have a leather kink, then you feel aroused by people wearing leather, but you can still feel aroused without it. It just enhances sexual arousal. A leather fetish, on the other hand, would mean that you require leather in order to get aroused. Honestly, this
site explains much better than me.
I'm mostly just asking out of curiosity. If they are fetishes, then do you need all of them to get aroused, or does at least one of them need to be there in order for you to reach a point of sexual arousal?
You dont have to answer if this is too invasive. I, for one, am a complete degenerate with several kinks (some of which actually make me feel kind of disgusted with myself), but I don't have any fetishes. Don't know where some of them come from, meanwhile others come from me reading too much fanfic and doujinshis.
