Cue Laura Ingraham's "ooh, my head hurts." So s/he (no, I don't mean Laura) is attracted to men and has the appropriate plumbing to attract men. But s/he claims to be a gay man so s/he would be attracted to gay males. But they wouldn't be attracted to her (from their perspective). So ... assuming s/he can finally attract a gay man and engage relations, where ... how ... never mind. She'd probably end up convincing her partner he was straight after all.
There once was a queer from Rangoon:
Took a lesbian up to his room.
They dicked all night
As to who had the right
To do what, and with which, and to whom.
