When I was 16, I would go into my bedroom and close the door and play with my dollies. I obviously sensed that at 16, I ought to have "grown out" of playing with my toys, but I did not feel that age and so, it was a bit confusing to me.
I believe I got tired with toys when I hit 18 or even a bit longer, but that probably was because suddenly I felt a very adult emotion and did not realise it, until I was 19, that I had fallen deeply in love with my boyfriend, who I had started to date when I was half way through 18.
Now at a nasty age of 48, although I have no desire to play with toys; my behaviour with how I react to things that bring me pleasure, I detect is very childlike. I squeal in delight and jump up and down and from what I gather, chaps find this endearing, but females find it repulsive, but hey, I do not get on with females anyway.
