Perhaps she is truly a homosexual and the amount of pressure one must go through in society can certainly make someone unstable. I disagree in that homosexuality is a mental illness. Yes, there are flaming drama queens and the list goes on, but at the same time the heterosexual society has it's share of wack jobs.
Interestingly enough Sigmund Freud believed that humans were bisexuals until their experiences with their parents, peers and then became either hetero or homosexual.
I have seen animals that are bisexual. Interesting. I don't condemn, nor condone it. It is what it is and here to stay.
I may be a Conservative Christian, but I personally believe that being gay is obviously different. I'm different, I'm bisexual, so in my life, Freud forgot those that remained bisexuals? hmmm...I wonder what he'd think about that? My cousin (God rest his soul) was gay. He died at 15 in an terrible accident.
I suppose it you're missing a phallus and you cannot use it was meant to be, then perhaps just knowing that it was there, it could make someone feel complete. Perhaps it pleases her partner..or who knows...there's plenty of sexual acts that are performed between a woman and a man that only one person is receiving direct pleasure...although, the other person is receiving pleasure from seeing the other person being pleased.
