When I was 8 years old at my cousin's(9 years old) house in 1996. We were bored and my cousin asked his mom to show us their family photo album. We eventually got to a picture of his older brother when he was a baby, crying and naked with a bandage wrapped around his penis. My cousin asked his mom what was wrong with his big brother's penis, she said "that's right after the doctor did something to his dicky-bird, he cried so much, I told the doctor not to do yours when you were a baby , Jordan had it done though". It was such an awkward moment even for an 8 and 9 year old, the conversation stopped after that. I never learned of the word circumcision that day, but I did learn that some boys get something done to their dicks. I always noticed me and my cousin had different looking dicks, but never thought much of it until that day.
Ever since my aunt told me about it, I was obsessed, at age 8, the fetish began. I started leaning over my bed and humping it while fantasizing about a doctor and nurse making my dick look different, re-enacting this mysterious thing that happened to my penis when I was a baby. I think it's because I grew up learning that my penis was a special body part, so a doctor wouldn't do anything to it, right? It just seemed so.....naughty, and it turned me on as a kid.
I learned about the actual term a year later when I was 9. I was a total mommy's boy at the time, she still dried me off with a towel when I got out of the bath tub(embarrassing but true). Usually I would flinch when she would do a quick wipe on my bare glans with the towel, and one day she asked me why I flinch, I said "it's a boy's weak spot, mom!" My mom then said "you know, when you were a baby, I had you circumcised. That means the doctor snipped the skin off your dicky-bird, maybe that's why it hurts when I wipe it." I asked her why I had to have that done to my penis and she said "you didn't need it done, mommy just wanted to have it done to you because it is healthy for boys and looks normal". I rushed out of the bathroom with a major boner, I couldn't help it, this made me terrified yet excited at the same time. I humped the bed just thinking of this new information, I finally learned what it was called and what was done to me as a baby.
There was no going back at that point, it escalated from there and I largely attribute my mom for keeping the fetish alive, I had suspicions of her having the same fetish as well. One time she was watching The Fifth Estate(a Canadian version of 20/20, basically a news story show). It featured the infamous David Reimer case, who had a botched circ and was raised a girl. I walked out to the living room and asked her what she was watching and she said "it's about a boy that got circumcised, but the doctor burned his dicky-bird off by mistake, so he was turned into a girl. The doctor never burned yours, he used a clamp to cut the skin off."
