If you are questioning your sexual orientation: look at your hand. If your ring finger is longer than your index finger (like me), you are most likely straight. If your ring and index fingers are the same length, no offense, but you might be gay/bisexual.
How this works: The more testosterone you are exposed to in the womb, the longer your ring finger will be in comparison to your index finger. If you aren't exposed to enough testosterone for your ring finger to be longer than your index finger, you have a higher probability of being gay or bisexual, as more testosterone exposure prior to birth = higher likelihood you will be straight. No, seriously, this has been proven.
I hope this was helpful. :)
