Just wanna talk about this

Y'all know guys how Manga reincarnation does, they got new body or born as a baby, but some times there's reincarnation where a man turns woman but never a woman turns man, and this is my question, if this man to woman and woman to man turn into romance would that be yaoi and yuri? But people on the internet says that if a trans woman married a man isn't gay and the same as a trans man so does that mean that those reincarnated people whose has opposite gender in their past life?
