i feel like because i accepted that i maybe open to sexual experimenting with a girl in the future i have to label myself as bisexual and sex with my boyfriend is feeling so off like i had a panic attack today. i haven’t experienced this in almost a year.

Sis, I don't mean to call you out, but you know you're seeking reassurance :) look, yesterday you had made peace with yourself and you said "I don't really care what I am, all I know is that I want to be with my boyfriend and maybe one day I'll want to experiment." You don't need to label that at all. It's called a normal, healthy understanding of your identity. No one here is going to point fingers and call you a lesbian or a bisexual unless YOU label yourself as that. Let me tell you a quick story: Once I had a good friend, we shall call her Kayla. She came out to me as a full blown lesbian at PizzaHut one night. I said that's fine, you do you. She dated one girl and then never dated a girl again. She has been with a guy now for the last 4 years. She seems happy with that. In her mind, I later found out, it was more of a fantasy of being with a woman rather than reality. She went through a phase and so did her sexuality. No big deal. So, you see, we could easily label her as something, but we don't. As far as I understand, she identifies as a fully straight female just like you, but likewise, had a few details that made her believe she was gay. Let me clarify and say that you DO NOT have to experiment to understand your sexuality. You choose what is comfortable for yourself. No one here is going to give you an answer or judge you or label you or condemn you. I suggest you spend some time doing productive distractions such as school/college work, exercise, painting, playing instruments, etc. You seem to need a break from this response and one way you do that is by refreshing your brain by doing something active. Much love to you and try not to make this something so black and white. :)
