I am 16 now and discovered about asexuality and aromanticism about 6 months ago. After sharing the same reasons as you and realizing my past history of incomprehension with romance and sex (I remember an argument I got into about abortion because I couldn't for the life of me understand why people always said abstinence was impractical), I accepted the labels as they fit far better than straight etc.. ever would. It actually took a fair number of conversations (mostly with by bi and lesbian friends because no one else talked about this stuff) because I was reluctant to "constrain myself" and I had always imagined marrying (in a relatively platonic way) and having kids, but I think it would have been disingenuous for me to keep deceiving myself.
So since you sound similar to me, I would hazard that there is a very good chance you are aroace but that is really up to you to decide
(Sorry for the convoluted sentence structure and parentheses everywhere I'm totally a concise and articulate person 😂)
