Do you HAVE to treat vaginal atrophy ?

I don’t have it, not even on T yet, but whenever people talk about vaginal atrophy they make it sound like it’s just a lack of wetness that makes sex hurt, is it?

Me personally I’m asexual, entirely sex repulsed and don’t even use the hole for anything at all, so if I got atrophy I feel like it wouldn’t really matter at all unless it’s more than just a lack of wetness. Like does it do anything else or does it just make using the mancave hurt.
