Not sure where I fall on the fetish-paraphilia spectrum. I used to think I "lost" my drive for vanilla and that tickling took over, but upon further review of my pre-teen years and puberty, I never desired "normal" sexual acts. Not once. As a young child, for some unknown reason (at least for now), I became "stimulated" at the sight of barefoot women, then barefoot women tickled, then when puberty set in, it became sexualized and the tickling urge spread to other body parts. So for some, needing it was never a question. "It" was all I ever wanted.
