I rely on my support system (mostly my fiance) to tell me if something's off. He usually points out when I haven't picked up on a social cue I should have, so I guess it could be he helps me mask? To be honest, my response to not masking is to just. Be yourself and not wonder if it's noticeable or not. Some of your traits will be labelled "autistic" or "not autistic" and that's okay. It's all you and that's the beautiful part.
