Well, just to weigh in, my ring fingers are CLEARLY longer the left one even moreso, and I identify as bisexual. That said, I'm very feminine in appearance, have always FELT feminine, am only attracted to boi-ish women and never really was aware of attraction to women until I ended up in the sack with one for a few years, and am now happily married to a guy. STILL I tend to think the finger thing isn't too scientifically valid. Something as quantitatively measurable as that would surely have attracted much more attention in the scientific community by now if the statistics bore it out as a definitive test. I'd accept that LBGT's are more likely to have the longer finger, but not that the longer finger always or even generally predicts LBGT identification. Way too many factors in sexual identification to balance it on one (albeit long) finger.
OTOH, I can now blame my PCOS on my mother for exposing me to testosterone in utero which perhaps means she will stop nagging me about not producing grandchildren as if I had talked my ovaries into it. I'll go ahead and point out that the bisexuality can be chalked up to her, too, since she tried to slather on the guilt about that, too (kind of ironically because she assumed a hetero relationship would equal grandchildren, I think. Ha.)
