Dating help

Hi, so I’m a bisexual girl and and everyone I meet or know don’t believe me. I’ve been with guys my whole life just because every partner I’ve had was right at the time and I really like them, but my friends believe that because I’ve only been with guys that’s all I’m interested in. I’ve tried multiple times to date girls but a lot of gay girls just think I’m experimenting and not serious. Just because I show a lot of interest in guys doesn’t make me not bisexual, I still fall fully madly I love with girls. Does anybody else have this struggle?
