Around 10 years old I saw a show on tv and a woman lift a man when she dance with him and I was friend with my female neighborn and she was a year older than me and taller than me and I asked her to lift me and she lilted me in front carry and I was very excited. After that my female cousin was 2 years younger than me and a little bit shorter but I often sit in her laps and she accept to liftes me in front lift and one time on her shoulders.

At age 7
 

When i was 7, i used to play with my neighbour girl with 1 year younger than me. She lifted me many times. Usually i wanted to prove my 'manliness' by lifting her as well. But i always secretly loved the other way around.
I watched some cartoon scenes which triggered me into this fetish. Like, wonder woman carrying superman in justice league cartoon.
there was a live action show called 'power rangers mystic force', where the skinny girl cradle carried the tall guy. It blew my mind when i was kid.
Then i have another trigger, when i saw beth phoenix lifted santino marella in a match in wwe. It was really unexpected for me, cause i didnt know about beth being that strong.

When I saw Chyna lift a refree with one hand

Guess I was born with it.

I was always shorter than average and much skinnier than average. I’m 5’11” and 200 pounds now. You might be on to something with the developmental self-image or perception. That makes me think.

I think about 20 is the age I started liking lift & carry stuff

As young as I can remember. Used to watch a lot of cartoons as a kid and seeing on there in a numerous sort of way is definitely what initially created my interest in it.

Good question.
Probably for the first when I watched cartoon with strong girls sometimes carrying men, like She-Hulk. Or Diane stopping rocket - that was fantastic scene too.
But it was in subconscious. I understood, that lift&carry is my fetish in middle school (14-16 years old) when I saw girls giving piggyback rides to some of my friends. Cool guys only and... I was too ashamed to ask a ride too. Now I'm 31 years old and still don't know this feeling ;/

As young as I can remember for sure. Definitely got the idea and interest from some of the super hero cartoons I used to watch as a kid. Not sure why it stuck with me for so many years. Kinda interesting to think about

I think already 10 years old is when I first started to really get into it. I’m not really sure where it came from tbh. Probably tv shows? Or just a fascination with strength in general.
