It is impossible to say exactly which and how many fetishes there are. Because there are millions.
There is no definitive answer to this question as it largely depends on what people are interested in.
Roughly speaking, we humans can "fetish" almost anything. From body parts like feet and hair to objects and materials like denim, leather, latex and even plastic! The possibilities are almost endless. So if you can think of it, it probably exists.
Although there can be some social stigma associated with fetishes, they can also be incredibly fun and enjoyable.
