Questioning my Sexuality and Gender

Hello. So I have. A lot of questions. I grew up in a relatively conservative Catholic household with my parents and younger brother. Now I want to make clear that I love my parents and I respect their decisions when raising me. I didn't know anything about Lgbtq until their was a gay marriage movement in our country and I saw it on the news. This was a complete shock to me as I had no idea that existed. My parents explained that being gay was when two men loved each other like a woman and a man do. I understood that and continued on with my life. I was under the assumption that gay people where very rare and I was probably never going to meet one. Then I moved and changed schools. My new friend group was filled with people different then anyone I had ever met. Strange words where thrown around like lesbian, queer, pansexual, Trans. I was very confused and asked then some questions. Over a period of time I have found out a lot of things from my friends but now that its openly discussed in my home I have discovered that I don't think my parents are the biggest fan of it. They constantly shared their opinions about how "they are all just faking it and looking for attention." So I was very confused. My friends (who many of them are Lgbtqa) didn't seem to be seeking attention or faking it? I didn't say anything to either party. After many discussions with my friends we came to the conclusion that I am probably Asexual. I did a lot of research and I also think that to be the case. I don't find either gender sexually attractive in anyway and I mostly just find the idea of sex and sexual activity boring and gross. But I have also discovered that I seem to have a ABDL fetish. Is it possible to be Asexual and still have a fetish? Like its really weird I know and I have no idea why I am like this. Eventually I sat down with my parents and told them I was asexual. They accepted it and asked a few questions. My mum was pretty much immediately trying to 'prove' why I wasn't. Like the fact that I have never had sex, so 'i just don't know what its like'. I felt a bit put down but ignored them. They seem to have completely ignored the fact that I came out to them as asexual as they still ask me occasionally stuff like 'when are you going to get a boyfriend.' And 'i can't wait for you tk have kids so we can be grandparents.' Its pretty disheartening. Now I have begun to do a bit more research and I think I might be nonbinary. I have always not been your average girl. Like I hate girly things and I always preferred boys clothes and boys toys when I was younger. Now I am beginning to realize just how different I act compared to the girls at school. I hang out with some other nonbinary people at school, because I just feel like I connect with them more. My parents have been getting more and more mean towards transgender people whenever they come up in conversation and I am worried how they will react if I come out as nonbinary to them. I am also worried about my brother as he has started to copy them and have the same thoughts and beliefs about lgbtq people as well. Any advice?
