In your OP you said that you’ve known since you were 17 and perhaps had some hints about yourself as far back as puberty, which seems perfectly reasonable.
I was wondering what your opinion is on those rare cases you hear of much younger, prepubescent children who identify as the opposite sex (which I think is okay in and of itself), who have parents who provide them with treatments such as hormone therapy and puberty blockers, which I think could be potentially quite harmful to a child’s development. Especially if it turns out that the child changes his mind and is not trans after all.
I mean, I remember liking girls at the age of six, but a lot can change between the ages of 6 and 12.
Thanks.
