Started masturbating and having kinks very young

This is something I've always been ashamed to admit in the past. When friends would ask when I discovered masturbating, I'd always lie and say the usual age. The truth is, I can now recall rubbing myself starting around age 4. I was insatiable and would even do so in public, in front of family members, in the shower, with pillows, with stuffed animals... multiple times per day. Probably even more than I masturbate now.

I remember laying in bed at night day dreaming up complex fantasies around 6 years old. Anything from gangbangs to doctor/patient roleplays to bdsm and being restrained. No idea how I had these ideas then. Im currently working through a lot of past trauma, but just wanted to share this incase anyone else shares a similar experience or has felt ashamed about it in the past.
