He Cut His Hair and I'm Trying Not to See Him Differently

So I need to get this off my chest. My boyfriend went from having hair that was 2 and a half inches long always styled and if not it looked great in a beanie. A few days ago he got his hair cut off to a crew cut, but slightly shorter. Very short actually and he even said he wouldn't go back because she cut off way more than he wanted. Now my problem is two things; this haircut reminds me of authority figures and that's a huge turn off (dries me right the fuck up), as well as... let's just call him rapist #1's hair. So much so that with my PTSD it completely hit me and I couldn't see past it no matter how hard I tried. I'm a really honest person so I told him all of that and kept apologizing for crying about it (had a flashback and poor guy didn't know what was happening). I feel so shallow about this, its just hair, and with any other haircut I wouldn't care I just look at him and I see not only a stranger but a violent one even though I know he's actually my very loving, very cuddly boyfriend... when we first met I hated his guts and he wasn't my biggest fan, and until now I blamed it on his attitude (he was at a bad point in his life) but now I think it may have been the stupid fucking hair... I can't help that I look at those haircuts and feel fear (he's also 6'3 so he goes from being a giant puppy to a person I feel i need to watch my back with). I know this is probably really uncommon but has anybody had a similar situation? He sat there and asked if I wanted him to wear a hat or something while it grew out so I wouldn't be scared, I don't deserve him. I just feel like he deserves better than this.
