Probably around 5th grade I realized I was bi because I was having crushes on female classmates. Then in like high school I realised I was asexual and then I kind of forced myself to believe I was demisexual. I didn't like the idea that I couldn't feel that same attraction as other people so I was like, ya know what, if I can connect with someone I think I can feel that way. But nowadays, I'm 23, I don't really care for how different I feel from other people and confidently can say I am asexual aromatic. But we are ever-evolving so I would not be surprised if I feel differently in the future, and that alright.
Be gentle with yourself, you have a right to be here.
