Most people think being bi means that you like girls and boys both equally, both romantically and sexually. But that’s not the case for everyone.
There are bi people who lean way more to one side than the other. There are bi people who experience sexual attraction to some genders and romantic attraction to others. There are bi people whose sexuality fluctuates. There are bi people who become fixated on one gender depending on their love interest. There are demisexual bisexuals, there are ace and aro bisexuals.
Not all bi people experience the same kind of attraction to each gender equally. We’re still valid and we’re still bi.
