Long hair is a marker for physical good health, is a feminine appearance marker and the overwhelming majority of men are attracted to long hair. Most husbands react to their wives lopping all their hair into some sort of short pixie cut quite badly. Kinda the same way you would react if he suddenly announced he’d shortened his cock to two inches long. You’re not going to really say anything, just make that strangling sound in your throat and hope that it can eventually grow back.
And yes I know, long hair is more work to take care of. Yes I know washing baby puke out of your hair is disgusting. Yes I know having a toddler deciding to latch onto your hair and rappel down the back of the couch is annoying.
Men really like it though. Shoulder lenght is just fine, anything past your mid-back starts seeming to be a little long. No need to go Rapuzel on us.
