But you’re not the only guy this has ever happened to, and only you can define your sexuality. For years, study1 after study has found this to be the case. Interestingly enough, the number of people who report having experienced same-sex behavior or attractions is way higher than the number of people who actually identify as gay or bisexual. Clearly, the term “straight” isn’t quite as straightforward as it seems. Sexuality is complicated, and labels can’t possibly encompass all of the intricacies of individual human desire. Attraction is complex and surprisingly fluid, even for straight folks. This is not an either/or type of situation—you could be somewhere in between, as many men are. One 2015 report found half of people between ages 18 and 24 say they’re “not 100% straight.” You’re the only person who can know for sure. “The reality is sexuality is expansive and diverse,” Baratz says. “Just because someone identifies as straight doesn’t mean that they can’t and will never have romantic or sexual feelings for an individual of the same sex.” This fluidity goes both ways, he adds. “One person who identifies as gay may also have sexual or romantic feelings for women. There isn’t a universal definition for any sexuality.” Identities like “straight” and “gay” may seem concrete and permanent, but in fact, research shows4 they’re subjective and can change over time. “Straightness, just like gayness, is an individually defined subjective reality,” Baratz says. Moreover, there are lots of other categories to choose from—there’s a whole spectrum of sexuality between the extreme opposites of gay and straight. Here are some of the most common ones. The scale shows that sexual orientation is far from black and white; instead, it shows sexual orientation as existing across a spectrum. Here’s the full Kinsey scale: 0 - Exclusively heterosexual 1 - Predominantly heterosexual, only incidentally homosexual 2 - Predominantly heterosexual but more than incidentally homosexual 3 - Equally heterosexual and homosexual 4 - Predominantly homosexual but more than incidentally heterosexual 5 - Predominantly homosexual, only incidentally heterosexual 6 - Exclusively homosexual X - No socio-sexual contacts or reactions The Kinsey scale isn’t perfect, but it can be empowering to think about where your sexuality falls along this spectrum and how it may have changed over time rather than leaping straight to “straight,” “bi,” or “gay.” The Kinsey team’s research shows that being 100% heterosexual or homosexual is rarer than you might think. Many online quizzes exist to help you figure out where you fall on the Kinsey scale. No online test is officially endorsed by the Kinsey Institute, though, and you can identify with whatever number feels comfortable to you. One possibility is “mostly straight” or “heteroflexible,” meaning that you’re usually attracted to women but occasionally experience feelings or desires for men. Savin Williams, author of Mostly Straight: Sexual Fluidity Among Men, calls it “straight with a dash of gayness.” Being heteroflexible is more common than often assumed; Williams cites evidence that more young men identify as “mostly straight” than either bisexual or gay combined. Mostly straight is a discrete category, distinct from being a closeted gay man or bisexual. “Strict rules don’t apply,” Williams writes for Time. “These attractions are sexual, romantic, or both and can be expressed in various ways, from erotic fantasies to actual behavior.” There’s a common assumption that bisexuality isn’t real; it’s just a stop on the way to gayness. But nothing could be further from the truth, and that line of thinking can be quite damaging to all bisexual people and particularly to bisexual men. In reality, 2% of men in the U.S. identify as bisexual, per Gallup News. “Allowing yourself to explore your sexuality and be curious about yourself, while minimizing judgment, is incredibly important,” Jor-El Caraballo, licensed therapist and founder of Viva Wellness, tells mbg. “Sexuality is complex. It’s both visceral and psychological. The biggest sex organ is the brain! Explore in ways that are more comfortable for you, like books, videos, or movies to see how you feel.” Most importantly, you don’t have to figure it all out by yourself, nor do you have to dive in headfirst. Caraballo says, “Apps and chat rooms can be good for a first foray into a sexual experience with another man, as you gauge your comfort level and work through any internalized shame.” A professional therapist who specializes in sexuality can also work with you to provide individual support.
