I started giving myself enemas (never got them from my mom or dad or other relative/neighbor etc) with a bag I found in my parents’ bathroom closet at the age of 5 and I realized that the feeling of having a nozzle in my anus and the sense of fullness in my tummy, and the relief that followed, were glorious. When I was about 11 I made a “dildo” using a large, thick sharpie covered in paper towels and wrapped really tight in Saran wrap. It must have been 1 1/4” thick. I discovered that my brother had condoms and used them to cover the “dildo” to extend its life and keep it clean (my brother was never involved in any of this!). One fine night, after playing with the dildo in my vagina something like a eureka moment happened and I wondered what it would feel like if I tried to get it inside my ass. I don’t remember what I used for lube but it was definitely not the most comfortable and not enough (I later started using whatever mild moisturizer I could find) but it got the job done. I’m small framed and I was a really petite kid at 11 and the dildo was very big for my little anus and it took some patience and effort and, dare I say, a few seconds of what I would kindly describe as intense, sharp discomfort to get it inside my butt. The sharp pain almost took my breath away for a few moments but something told me to leave it there instead of taking it out (I probably thought it would hurt more to get it out right away) and just try and relax a little. The feeling that I experienced was similar to the sensation of having the enema nozzle -a garden variety long and thin one, the kind that comes with the most basic bags- enter my anus, except much stronger, and there was a very warm and pleasant sense of fullness, albeit different from what I knew enema fullness to be like.
I might have used spit to lube the dildo some and I started masturbating myself with it by pushing it in and pulling it out -I had just started having vaginal orgasms doing the same movements with the very same dildo, and I had recently discovered that touching my clit at the same time resulted in even more intense pleasure- and then I must have found a position where I could hold the dildo with one hand and tease my clit with the other. It felt like nothing I had ever experienced before and, almost before I had a chance to realize what was going on, I had what I believe was my first anal orgasm, a whole body, toe curling (that part freaked me out a little coz I was not sure why my toes had any business curling during this process, but I got over it fast) “omg-this-feels-so-amazing” affair. It was a few orders of magnitude better than a vaginal orgasm and even at the tender age of 11 I had no doubt that, while I could derive pleasure from either, anal stimulation and play were what I wanted and craved.
It was not until 6 years later that I actually had sex with a partner and I had to wait another year before I met someone who gave me anal sex for the first time (my first boyfriend was a virgin like me and was not sure he was ready to go that route; the man I first had anal with was a little older and more experienced but not much). That latter experience definitely helped me understand that I was much more anal than anything else and now, at 39, ie 21 years later, I know that I would be absolutely fine if I only had anal sex/enemas/fingering/fisting or other forms of stimulation -maybe with a little bit of clit tease thrown in for variety- for the rest of my life.
