Nail polish for my boyfriend?

My BF got me a mani-pedi package at a local spa for my birthday and for fun I got him to come too. They buffed his fingernails but did his toenails to match mine – sort of a coral pink shade. I loved it and he actually kinda dug it too. I’ve made him keep his toes painted since (it was last weekend) and I’m thinking this summer I’d like to have him wear toenail polish regularly. I’d like to know if other couples do this. What shades do you use on your BF/husband? What kind of sandals does he wear? (I wear Dr Scholl’s all the time in summer and I’m thinking of getting him a pair.) How do friends/family react? Should I keep his toes painted all the time or just for special occasions?
