I sort lf question my sexuality in the past two years, when i start to take a liking on one of my class mates. I just findd her so attractive, so different from other girls. I get that kind of feeling like butterflys in my stomach when Im around her, no one had made me felt like that before, and I want to be with her in a romantic and sexual way. I told my mum that I find that a class mate of mine is very pretty, and I always caught myself smiling when I'm talking or thinking about her. My mum seems to notice and told me that I cant like girls. Its wrong. Im not sure if im bisexual but I know that part of me is a lesbian. I have never liked or have a crush on a guy before, but I have with girls. I want to come out to my parents that I'm definetely not straight. How should i do that? Or should I come out? Or wait when I'm older and more certain before coming out?
It's your choice if you want to come out, but it'll be very difficult if your parents are homophobic. Here's a link that might help: Coming Out to Your Parents - Gay, Lesbian, Bisexual, Transgender, Queer, Questioning, and Ally Resource Center I think the "Questions to Ask Yourself" section would help you a lot. It's something to think about before coming out. Good luck.
How old are you? You mentioned class mates so I'd assumed quite young. If there's no way for you to care and provide for yourself if your mum has a bad reaction, I would wait until you're 100% certain you can keep yourself safe, as you don't want to find yourself stuck in an uncomfortable or unsafe home situation.
