Yes, but i always make sure to first fantasize about having my mind and body regressed to being 14 by a mad scientist. But then, when i was 14, my fantasies were about Wonder Woman, so my thoughts go there. But she was a defender of lawful behavior so she wants nothing to do with fantasy me, so i fantasize about a sane scientist advancing my age to match my target demographic, but when i was the age Carter was during production i married my wife, who is beside me, so i don't need to fantasize, so i just go back to normal and live my life.
TL;DR Ever? Yes. In the last 40 years? No.
