That's actually not accurate lol a lot of people do gay shit or ''try'' but aren't actually gay, or not fully at least. There are so many girls who will kiss girls when they're drunk at parties, but they won't actually have sex with a woman or date a woman. I've seen men do the same thing. I dated a guy who would kiss guys at parties but he was really not interested in sex with men, he told me the experience he had of a man sucking his dick wasn't pleasant for him, but he still identifies as ''queer''. He was really milking it to appeal to girls lol which is ironic, but it works. A lot of women like men who are a little bit gay or feminine.
Even when it comes to clients, I've had a lot of men confide that they were excited by sucking dick or having their dick sucked, but they didn't like anal sex and only were interested in men for brief encounters. Others have told me they have sex with men sometimes but they're not interested in them romantically.
Sexuality is really complex. It truly is a spectrum. A lot of people are bisexual but prefer a certain gender, or it fluctuates and changes over time. Societal pressures also kinda dictate who we prefer. It's much easier to be in a heterosexual relationship in a way, because we know the ''script'' for it, socially. When I started dating women for real, I had to learn a new way to relate to another person in a romantic relationship.

I didn't feel comfortable dating women until my mid 20's.. I had a lot of internalized homophobia to work on.
That being said I'm not a huge fan of somebody pressuring someone into doing gay stuff and ''trying to turn someone gay'', it doesn't sound consensual. I would never pressure a woman to do anything with me. Even when it comes to duos, I am really uncomfortable accepting one with somebody who I suspect isn't bisexual.
I think labels can be useful sometimes.. instead of the word label I'd use the word ''identity''. but I get the sentiment
