No, I don't think that "imprinting" -- in the sense that ducklings imprint on their parents -- would be a cause of crossdressing, or transgenderism. There are probably lots of guys who had similar experiences as an infant or toddler, but never have the urge to CD. I do think that most of us who are TG (CD thru TS) were probably born this way, perhaps through chemical influences in the womb. So we have the built-in responses there, and when we first feel that silken scarf, or put on our first pair of panties, it's reinforced.
At least my :2c:
