On the fetish post, I discussed people who had some early sexual experience - like seeing a sexy cartoon character - and reacted in some profound way, like becoming a furry. Sometimes people have described this as a "critical window" for sexuality (similar to the "critical period" in language learning?) where young children "imprint" on sexual experiences - and then can't un-imprint on them later, even when they see many examples of sex that don't involve cartoon animals.

One of my distant cousins won't eat tomatoes. His parents say when he was very young, he bit into a cherry tomato and it exploded into goo in his mouth, and he was so upset he wouldn't eat tomatoes from then on. Now he's in his 30s and still hates them. Is this fairly described as a "critical window" for food preferences?
