I am strictly DL, not AB at all and I wear 24/7 but don't use at all, not even for wetting! Yes, you probably think that i am a bit of a freak but I wear for pleasure and also because my relationship is Master/Slave with my husband so control is very much an aspect of our lives. I always wear Tena Slip Maxi and like you I am quite petite (5 2") but they fit me perfectly. As for 'time of the month' I use tampons so carry on wearing my nappies anyway. Welcome to the lifestyle by the way, I hope you get a lot of pleasure out of it
