At what age were you into L & C

[Error900]

I had a slight interest in being lifted and carried since I was very little. But it became a real fetishism when I was 10-11 years old and my aunt gave me a piggyback ride. My parents weren't at home for some reason and so she was looking at my little brother and me. So at some point she started playing with my little brother at the horsey, carrying him for the house. Looking at them I wanted to ask her if she could give me a piggyback ride too. I was very embarassed at the idea, because i was 10 and i wasn't a little kid like my brother. But in the end I asked her and she unexpectedly said yes telling me to get on the sofa so that she could have taken me on her back. So she carried me around the house for very long time (because I didn't want to get off XD) and the best part was when she started hopping around with me on her back saying "horsey-horsey-horsey" as if I were a little baby. I was so embarassed and happy at the same time and I had one of my first erections in that moment.
Unfortunately now I'm 20 and I haven't had any other experiences of this type since that fateful day...
