Nylon/ foot fetish

My husband and I have been together 8 years. He casually mentioned when we first started dating that he liked me wearing nylons. What he failed to mention is that he wants me in them 24/7. To sleep in, cook in, shop in, have sex in. ALWAYS on. First thing he checks when he gets home from work... Touch my butt & legs to see if I'm in nylons. If I'm in them. I get a " Good girl." Along with a lot of kisses, playfulness & some days sex!!! If I'm not wearing nylons he gets turned off. Goes about his business & isn't interested. If they start hurting my toes & I pull them off at night when we're sleeping. He won't cuddle with me. If I have them on at night during our sleeping time. He rubs on me, pulls my feet to his chest, rubs my feet & cuddles me all night. Has anyone else experienced this? Is this a common thing? I'm all for trying new things and experimenting. I go along with it because I love the benefits I get from pleasing him.
