married fun

so i been married a while now and we always had this thing where we play around with ageplay kinda stuff. its not hardcore or anything but like one day my husband told me he wanted to be my little for a day and it was surprisingly hot. we did all sorts of little things, asked me for candy, refused to eat veggies, watched kid movies together, the works. afterwards i felt so connected with him and our relationship felt closer than ever before. do other married couples do this too? is that weird or just part of normal healthy fun?
