For these 14 celebrities, pansexuality is very real and differs from other LGBTQ+ identities. “‘Pan’ comes for the Greek word ‘all,'” Holly Richmond, PhD, a certified sex therapist and marriage and family counselor, previously told Women’s Health. “Pansexual is not bi-sexual, it’s all sexual.” That means a pansexual person could be attracted to a man, woman, a transgender person, or a nonbinary person (someone who chooses not to identify themselves by either gender), Richmond says.

With all that in mind, here’s how these 14 celebs who identify as pansexual explain the term.

“The older I get, the more I think that I’m nonbinary,” Van Ness said in an interview with Out. “I’m gender nonconforming. Like, some days I feel like a man, but then other days I feel like a woman.”

For years he considered himself a gay man, he explained, but he recently realized nonbinary is actually a more accurate description. “I didn’t think I was allowed to be nonconforming or genderqueer or nonbinary—I was just always like ‘a gay man’ because that’s just the label I thought I had to be.”

So what does it mean to be nonbinary, anyway? “Someone who’s nonbinary doesn’t feel like they fit into either the culturally or societally stereotypic definitions of a man or a woman,” Holly Richmond, PhD, a certified sex therapist in New York City, tells Health.

But not everyone who identifies as nonbinary is the same. “For some people, this means they always land somewhere in the middle. They’ll never say ‘he’ or ‘she,’ but rather they’re always in that middle ground,” Richmond explains. “For other people, it can be fluid. It can change week to week or month to month, depending on what they want during that time.” (As Van Ness told Out, some days a nonbinary person may feel like a man, but others like a woman.)

A nonbinary person might also see themselves as a man and a woman at the same time. Or they may consider themselves to be transgender. A trans nonbinary person is someone who doesn’t identify with the sex they were born with (trans) and also has a gender identity that isn’t strictly male or female (nonbinary). A nonbinary person who doesn’t feel they’re trans may, like Van Ness, partially identify with the sex they were born with but also have a gender identity that isn’t categorized as exclusively male or female.

Those who identify as nonbinary might also have a range of sexual preferences. “They might choose someone who’s gender nonconforming, they might always choose a male, always choose a female, or they might consider themselves bisexual,” Richmond says.

A nonbinary person can be as private as they want about their identity. But in some situations, they might want to make their identity known, such as at the doctor’s office. It’s important for all medical records to include sex at birth, gender identity, and legal sex, so a person can get proper care. Doctor offices unfortunately aren’t required to record all of this information—which is why it’s important for the patient to offer it.

Another thing it’s crucial to clarify: pronouns. Van Ness said he doesn’t identify as a man and sees himself more fluidly, yet he does use he/him pronouns. But everyone is different, so always ask a nonbinary person how they want to be addressed. And remember, identities can be fluid, so a person’s might change over time.

“Any opportunity I have to break down stereotypes of the binary, I am down for it, I’m here for it,” Van Ness said. “I think that a lot of times gender is used to separate and divide… I think any way I can let little boys and little girls know that they can express themselves… no matter how they present is really important and exciting.”

Most of us have experienced this kind of instant, almost primal attraction. But a small number of people never have; they’re incapable of it. To be attracted to someone, they need to develop a mental or emotional connection to the other person, not a physical one.

That’s a demisexual in a nutshell.

A demisexual is someone who is hardwired to seek an intense, solid, securely attached relationship before they can even think about sexual intimacy, Holly Richmond, PhD, a sex therapist in Southern California, tells Health. For a demisexual, intimacy is on a platonic level—at first. Sexual attraction develops as the relationship deepens.

“A demisexual is not going to walk down the street, see a hot guy, and think, I want to sleep with that person,” Richmond says. Celeb crushes, romcom flicks, love (or lust) at first sight? None of this resonates with a demi. “it just doesn’t make sense to them,” she adds.

A relationship for a demisexual typically starts as a friendship and may blossom into something more. Sex is still important; there’s nothing wrong with their sex drive. But what turns them on has to do with brains and personality rather than a toned physique. “They really need to know someone to feel sexually attracted to them,” Dr.Richmond affirms.

How would you know if you’re a true demisexual, rather than a person who just isn’t into hooking up or getting sexual with someone early on? Think about how your romantic and sexual relationships have started. If it took time to get to a place where you felt chemistry, and the lead up to becoming a couple involved lots of talking and platonic time together, you might be a demi.

It’s hard to know how many people are demisexual, especially since the term has only recently entered the lexicon. But Richmond believes that in the past three years, more people are using the word to describe their own sexual orientation. It’s similar to the recent uptick of people who identify as asexual (feeling no sexual attraction at all to anyone).

Yet just like those who identify as asexual, people who are demisexual can still develop serious, fulfilling, long-term relationships with others. They just get to that place in a different way that doesn’t rely on physical chemistry.
