How do you know if your bisexual?

I don't think there is ALWAYS a way to know for certain. If you feel an attraction to both the male and female gender this is usually a sign that you are bisexual.

I don't think you can truly 'know' if you are any sexuality, not just bisexual. I think that, if you feel like you are bisexual, then that's what you should go with and, if one day you don't feel like you are sexually or romantically attracted to both sexes, that's fine too. Sexuality is not a list of concrete categories. It's a spectrum, and we are all somewhere on that spectrum.

didnt really know i was till i learned what bisexual meant, just knew i was attrcted to both genders

If you are bisexual you are physically and romantically attracted to both the female and male gender. You could call this a "crush." You can have a crush on a girl or a boy to be bisexual.

Well, sexuality is a spectrum. Some people are both sexually and romantically attracted to just their own sex or just the opposite or of all sexes and genders. Bisexuality is also a spectrum. You might have had just the occasional crush on the same gender or sex, or you are just sexually attracted to them and not interested in a relationship, but you are interested in a relationship with the opposite sex or genders. Many people find that they are bisexual after reflecting on previous crushes and reflecting even on friendships and seeing if there was ever another feeling you had for them. No bisexual is the same. Remember, you could still be bisexual if you have only ever been attracted to someone of the same sex once and the opposite sex many times. At the end of the day, it comes down to however you personally want to identify.

Bisexuality is, for a definition, an attraction to two genders or more, but not all genders. If you feel any kind of attraction (romantic, sexual, or others) for more than one gender, it is possible that you are bisexual or biromantic. The only way to be 100% sure about it is to take your time. No rush ! You'll know who you are in time :)

Bisexual is when you experience attraction to both males and females. It doesn't have to be equal. You don't have to be 50-50 on male and female attraction. You can be 90% attracted to males and 10% females. Or vice versa. You can be 70% attracted females and 30% males. Or vice versa. You can be 99% attracted to males and 1% females. Or vice versa. As long as you experience attraction to both males and females you would count as bisexual. (There are many other sexualities that also include male and female attraction. Bisexual means ONLY male and female attraction. Polysexuals, for a single example, includes male, female, non-binary, genderfluid, genderqueer, agender, transgender, etc. And it varies from polysexual to polysexual.)

Everyone's different, so you may not realize it right away. You might see some guy in the hall and think "wow, he's so cute," and then five minutes later see a girl and think the same thing. Or it could take several months or years to figure it out. Bisexual means that you like two genders, which don't have to be strictly female and male. It might take some time to figure it out.

Sexuality can be a tough thing to figure out. I recommend to take your time figuring yourself out. There is no rush to define yourself.

If you are attracted to both sexes. If you aren't quite sure how you know, try to find someone of the opposite sex who you think is attractive. Then ask yourself if you would kiss them. If you would, would you date them? Would you have sex with them? then do the same with an attractive person of the same gender. If your answer is basically the same for both genders, you're most likely bisexual.
