No, we haven't all. I discovered cumming before either mastrubation or sex. Good luck figuring out how, and the shame of the realization hit hard. Took only most of my life to turn that around.

And yeah, I started with vore then tried furry r34, then vanilla, because I started my life ass-backwards. I progressed to asexual, rediscovered my thing for vore, and had self-hatred for it most of my life. Went for months without mastrubating sometimes.

Holy shit, the cum, the entire nights spent making up for those months, and the sheer kinkiness after.
