my ring finger is longer. (bi, aro, cis-female)
i'm pretty positive that the "digit ratio" thing is related to how much androgen a fetus got exposed to in the womb, so people with a small digit ratio (longer ring finger) are more traditionally masculine (aggressive, systematic, not very good at expressing emotions and so on). there are some articles online, if anyone's interested in reading more about it. btw, there's a wikipedia page on it, with many references, correlations and all that.
