I'm going to always ask my boyfriend to turn his laptop sound and brightness down when I'm trying to sleep and for telling him how anxious trapped and irritated asmr makes me when that is his guiltiest pleasure
Why do you need to tell him to turn it down?
Because he never takes my feelings into account, and I already asked him to stop watching asmr and he just doesn't care.
If he really enjoys the ASMR, you should let him do it, just in another room. It is not fair to take away something that relaxes him.
He's being the inconsiderate one here!
Trying to prevent him from enjoying something so harmless and inconsequential is lame. Just ask him to leave the room  when he's consuming ASMR content.
