To all gay or bisexual people? (Or even straight people if there are any here?)?

Bisexual female, 22. My index finger and 4th fingers are exactly the same length on my right hand. On the left (yes, they're different length, odd I know, lol) my index is quite a lot longer than the ring finger. Can't click on links because my phone is annoying but aren't those theories linked to testosterone levels?
