Bisexual Grandslam
Having had sex with 4 different genders (doesn't have to be at the same time but if you do kudos). Named similarly of the Grand Slam in tennis. Having had sex with one woman, one man, one non-binary person and one agender person. Once you have achieved this you will have leveled up your bisexuality.
