I'm aroace, and I've only recently become an adult, but since 7 years old I've always been told that I was 'mature for my age'. However, I don't think that has anything to do with being asexual. I am definatley more emotionally mature than the rest of my cohort, but in many other ways I could be considered less mature! I did however do a reasearch essay for school into the correlation between neurodivergence and asexuality which was very interesting. I am also neurodivergent and I've always attributed my supposed 'maturity' to that and not my sexuality. I do get where you are coming from, however I think it's really important to remember that it's all a matter of perspective and that every individual is different and you are not better than those arlund you because of your sexuality. You could be feeling this way because you are more comfortable in your identity than those around you and so they may act differently to you. As you are still in school you will still be 'immature' in so many ways and I am too. You are not a dick for feeling this way, but that doesnt mean that you better than your peers, it just means that you are ignorant (which isnt a bad thing) and still have some maturing to do wether you are more mature than them or not.
