Also meant to add, I don't think there is any one universal answer for any fetish or why someone has a fetish. I think within certain fetish communities you may find similar answers, but I believe the development of them is on an individual basis. The most important thing is to accept it and not feel shame, I know I struggled with a lot of shame for my love of BDSM, and it was because I struggled to accept that part of myself because of people's judgements or fear of people's judgements. But in the end I realized it was part of who I am and my sexual identity and I had to accept it and everyone else's opinions or pre-concived ideas didn't matter.
