Should I wait to come out as ace to my friends?

[dry beacon]

For some context:

• I'm 16, and my friends are all either 15 or 16
• I'm also biromantic, and I'm already out to them as bi
• Everyone in my friend group is lgbtq+ and very accepting (however as far as I know, I am the only person on the ace or aro spectrum)

We're a very open-minded and progressive group of people and I know that everyone is definently supportive of the ace and aro community. I just don't know if I should come out right now or if I should wait a couple of years. I'm scared that because of my age, they won't really believe I'm ace and think that I'm too young to know for sure and just haven't developed sxual feelings yet. I feel like if I was 18 they would believe me for certain and I don't know if I should just wait until then.
If I did come out now I would do it subtly - start wearing my ace ring around them, put some ace stickers on my stuff. The only person I would probably tell directly that I'm ace is my best friend, and he's made some comments that make me think that he might equivalent ace to also being aro, so I would have to explain to him how I have romantic but not sxual attraction and I don't feel comfortable talking to people I know about anything sxual.
Should I just wait until I'm older to come out to them?

tldr; I know my friends accept ace people but idk if they would believe I was ace due to my age

I personally think that because they are all lgbtq+ it is likely safe/alright to do so, because the same question could be asked of them. I say go for it (however you want to), but if you don’t feel comfortable then don’t

I'm pretty sure most non-ace people develop sxual feelings by 16. Unless your non-ace friends are "late bloomers" (stupid term but IDK a better one) and themselves haven't developed them, I don't see any reason they'd think you're too young. I think you should go for it :D
