"I thought you claimed to be homosexual genetically!...I still beg to differ!"

That would be unlikely, since whether or not homosexuality is genetic, I never tried it or wanted to.

There is, of course, the possibility that deep down inside I'm really a woman, but she's a total lesbian.

If you honestly thought I said I was gay, you just happen to have mixed up references; I never did anything like that myself. : )
