Discovering and understanding your sexual orientation is a personal and sometimes evolving process. It's entirely normal to have feelings and attractions towards different genders, and it's okay to take your time to explore and figure out your identity.
Sexual orientation, including being bisexual, is about who you are attracted to emotionally, romantically, and sexually. It exists on a spectrum, and it's not always a simple binary choice between being exclusively heterosexual or homosexual. Bisexuality means that you can feel attraction to more than one gender.
At 14, you are still young and have plenty of time to explore and understand your feelings. It's okay to have had crushes on guys in the past and also feel open to the possibility of falling in love with a girl. These experiences don't have to define your sexual orientation right away.
Give yourself the space to be curious and open-minded about your feelings. It's essential to be patient with yourself and not feel pressured to label or define your identity immediately. Your feelings may continue to evolve as you grow and learn more about yourself and your attractions.
If you feel comfortable and safe doing so, you might consider talking to someone you trust about your feelings, such as a close friend, family member, or counselor. They can offer support and understanding as you navigate your emotions and self-discovery.
Remember that it's okay to be unsure or to identify with a particular label, and it's perfectly normal to feel attractions to different genders. Trust yourself, be kind to yourself, and allow yourself the time and space to explore and understand your feelings at your own pace.
