So I believe I must be a HSP ( highly sensitive person) and further more Senonsory Defensive. 

When my sister lived with me a couple years ago she always had the volume up louder then my ears appreciate, she is hearing impaired, my mom is too and growing up the volume was always too loud so I just stayed out of the room with TV. I am blessed like my grandma with good hearing. My sister and I got into many arguments over volume. 

She moved out and now I live with my boyfriend. He is hearing is not so great so he has everything at full volume where I am on the entire opposite spectrum where I only need it up a couple of pegs on from mute. At work when I am listening to music I have it on some of the lowest volume. The only time I listen to something loud is when I am driving with windows down. 

So our daily volume works like this, he turns it up and it hurts my ears, I ask him to turn it down, we compromise on a volume then a little later when I am not looking he turns it up. I typically leave the room if I dont want to confront. 

What our biggest issue happens when we are in bed and he streams something from his laptop. He typically has it at full volume, I will ask him to turn it down to half, I would prefer it down to like 3 notches from mute but of course that would not work. He turns it down to half but then a couple minutes later he turns it back up and if I ask, he gets upset saying he can't hear. 

I can't sleep with the loud volume and I am someone who typically falls asleep really fast. If he falls asleep first I then have to deal with his snoring which is sometimes difficult. 

I have tried dollar tree ear plugplugs but I fear that if the apartment fire alarm when off I wouldn't hear it since I am a deep sleeper and the last ones that have gone off it took me awhile to wake up from. 
 
He doesn't like headphones and thinks I need to put up with it.

It rings my ears and even at this point I am in a different room then him and his football is blasting and its ringing my ears so obviously something must be wrong with me if my head is hurting and it's not even in the same room.

We also struggle with touching sensitivities where I dont like him touching my spine as it ends up giving me spasms, or he might lean against my back with his 300 pound body and that also triggers my back pain. Sometimes if he touches my arm it hurts.

I also dont need a lot of light and he keeps all lights on and I have to sleep with eye masks as he likes turning on lights in middle of night or just keeping them on. 

Smells also bother me, cigarette smoke, perfume, even coffee. Anything strong.

Which makes me think I am an HSP and have some type of sensory disorder. I just found out about this disorder the other day and he thinks that makes a lot of sense. I found a book to read on it but it's all just really frustrating because he says I am over reacting and justifies his needs over mine.

My boyfriend has trouble hearing the TV / Laptop Volume and wants it on very high.
I have sensitive hearing and want it down low.
Am I the asshole for wanting the volume down low where it may be difficult for him to hear the show?
