A lot of fetishes seem to be about control in one way or another. It could have roots in something unpleasant that happened to you, or it might be linked to something totally benign. If it were causing you psychological distress, a sympathetic therapist or psychiatrist could help you sort it out.

My personal opinion is that exploring BDSM could be a healthy and enlightening journey for you. Just play safe...there's quite a fetish community out there, and folks can tell you how to explore your desires without hurting yourself or someone else.
