See what there is in Pubmed about Aphallia. Not so much... but see how the older papers showed more female assignments....and the new male assignments... things are changing.... the understanding of gender identity formation is deepening!!!!

See the last papers about effemination (sissyboys) in Pubmed. When a sissyboy shows a gender dysphoria and when shows a homosexual tendency? That is a very good question! Also here, things are changing..... the mix up between homosexuality and gender dysphorias is diminishing.... with the increasing of knowledge about the differences.
