To me, this very much sounds like being aromantic, as to whether or not you will experience romantic atraction later, if you just keep waiting, i wouldnt worry about that. we never know what will happen in the future, but that dosnt actually change how you feel now wich is way more important.
tbh, i wouldnt stress to much about labels, if you dont wanna kiss people, then dont. there is no need to find the perfect label that is going to fit for all time.
as for how ive handled "doubt", i just stay true to how i feel right now, ive never experienced atraction, so until that changes (which it probably wont) i will keep on identifying as aromantic, <3
idk if this helps, i always feel like i just end up rambling lol :)
