"I'm bisexual."
REALITY: 80% of self-identified bisexuals are only interested in one gender.
OkCupid is a gay- and bi-friendly place and it's not our intention here to call into question anyone's sexual identity. But when we looked into messaging trends by sexuality, we were very surprised at what we found. People who describe themselves as bisexual overwhelmingly message either one sex or the other, not both as you might expect. Site-wide, here's how it breaks out:

This suggests that bisexuality is often either a hedge for gay people or a label adopted by straights to appear more sexually adventurous to their (straight) matches. You can actually see these trends in action in the chart below.
Again, this is just the data we've collected. We'd be very interested in our bisexual users' thoughts on this single-sex-messaging phenomenon, so if you'd like to weigh-in please use the comments section. Please note, everybody, that we don’t assume that bis should be “into both genders equally.” We only assume that they should be into both genders at all. The swaths of red and blue that you see in these sexuality charts represent people who message only one gender. The purple areas are people who send any messages, in whatever proportion, to both men and women. In this chart, throughout the teens and twenties, the male bisexual population is mostly observably gay men. By the mid-thirties, it seems, most of these men are more comfortable self-identifying as gay and have left the bi population. By the end of our chart, 3 of every 4 bi males on OkCupid are observably straight. Meanwhile, the proportion of men who message both women and other men holds fairly steady.
The proportions for women are more consistent over time: 12% of women under 35 on OkCupid (and the internet in general, I'd wager) self-identify as bi. However, as you can see above, only about 1 in 4 of those women is actually into both guys and girls at the same time. I know this will come as a big letdown to the straight male browsing population: three-fourths of your fantasies are, in fact, fantasies of a fantasy. Like bi men, most bi women are, for whatever reason, not observably bi. The primacy of America's most popular threesome, two dudes and an Xbox, is safe.
