I started putting found around the house objects up my ass when i was just a little girl. At first I would just stick them in , and pull them out. Nothing sexual about it. At maybe 10 or 11, I stuck my hairbrush handle in my butt, and it caused a sexual stirring. No orgasm, but I knew I was onto something. By 12, I discovered both lubricating the hairbrush, and masturbating. A momentous occasion. I still wasn't orgasming, but WOW, did it feel good.
My first store bought sex toy was one of those horrible hard plastic vibrators. I bought it in a dirty book store. I think the guy behind the counter was so surprised by a girl buying a vibe, that he never questioned, or maybe even noticed I was about 15. First off, I hated the vibrations. To this day I will not use a vibrator. It was also stiff, and would bottom out quickly, maybe 6 or 7 inches.
The first flexible toy I got was made of rubber, it smelled like an inner tube. (Remember this is the late 70's) It didn't flex much, but with some practice I got it into my colon. It was a great moment, that I discovered I didn't need any clit play. The dildo breaching my colon caused instant orgasms.
All in the path down the road to perversity. I never looked back, but i have questioned my sanity, as I sat down on a plug the size of a fire extinguisher.
