well,how do i explain? aro is a short form for aeromantic, which is when someone feels that they do not need to be in any sort of romantic relationship (such as crushes and stuff like that) and ace is a short form for asexual, which is when someone does not have any... intimate feelings for other people! i hope this helped you understand! and i just want to warn you now,even as someone who's been in this community for 3 months now, i still do not know everything about this community,but fear not,because i am always learning new facts about the lgbtq community!
