Bisexual?? Or something else

Saw this on another post but wanted to ask here so for a long time I have had this “ phases” where I feel attracted or maybe gay desires, like for example I don’t really imagine myself o think about having sex with a men but there’s stuff like example was at the dentist and had a female “nurse” and a male doctor attending me and whenever he pulled me close to him (turned my head and well “that” was close I kinda imagined what it would be like if he was trying to put that in my mouth. And at the same time I was interested in the “nurse” 😵‍💫 But most of the time I am totally into woman and don’t actually want to penetrate or be penetrated by a man 🫠 sucking on the other hand feels different 🫣 so I don’t freaking know anymore…also I love the fantasy of a threesome with my partner 2 male and her
