What age does lift and carry start on average
 

For me, it stated at 4. Did it start the for you earlier, by then, or later?

For me it started around 3 or 4 I guess. It's like it's always been there.

I'm guessing by your name that you like to be lifted. I don't. I would see women being lifted on TV and I wanted to be able to lift them, too. When I was in high school, the cheerleaders got me into seeing girls lifting girls. I never wanted to be the liftee. That was always a feminine role in my mind so the idea of being treated like I'm feminine was always repulsive to me. Over the last 25 years of looking at L&C online my reaction to F/M has dulled considerably. It still doesn't do anything for me but "repulsed" is way too strong to describe my current reaction.

I point all that out because at the age of 4 it's pretty normal to be carried so I could see a liftee liking it and wanting it to continue. For me I was already repulsed by the idea of being lifted and resisted my parents when they tried to lift me. That seems a bit more severe to me.
