Questioning my sexuality help needed please read

Hi I’m a girl. I’ve been identifying as bisexual for about a year now. But I’ve been online and I’ve seen some things that have made me question my sexuality. It’s been apparent that I’ve been attracted to women since I was a kid. I never had any interest in boys as a kid only girls. But I guess that can be a result of cooties haha. This is random but still kinda relevant, I cant imagine myself doing it with a guy I’m just not interested in it. It’s been the other way around with girls. I can’t imagine myself marrying neither a guy or a girl. I’ve had crushes on guys before but I’m only interested in a relationship and not having kids or doing it with them. I’m scared because as usual with people in the lgbtq+ community this world is not very kind to the lgbtq+ plus community. If my mom ever found out I would not be alive anymore.

Sorry if my grammar is bad English isn’t really my strong suit. Please ignore it.
