something sounds really fishy about somebody ‘unhappy with their female identity’ to be entering numerous beauty contests - which are pretty much all about female identity.
Mental Illness sounds appropriate though. This is somebody who hates herself. But changing her gender won’t make her a different person and it won’t make her a better person. And it won’t make her any less a lesbian.
If she sees herself as a “male” why didn’t she have her female partiner artificially inseminated? I think she has more than just gender identity issues...
