Same!!! I found I subconsciously read lips well enough with peripheral vision that I can look at most ppls' eyes when they speak, but I feel like I'm internally tracking how long I've been staring and when it's appropriate to look away for a second to avoid coming off as too intense. It works with everyone except my partner who is also autistic and says masking is a form of manipulation. So ig there's this range of eye contact where NTs feel comfortable, but that same range could be uncomfortable for NDs
