admitting something new to myself

so i finally admitted this thing to myself like a month ago and i feel so weird about it. i know im in my 40s and married but this roleplay stuff with my husband, its just come up recently. we were talking one night and he mentioned age play and id never thought of that before. now i find myself thinking about it all the time like how itd be to be his little girl again. hes always been the daddy type so its not super surprising but the idea of being submissive in this way, it just freaks me out a bit. im worried my husband will think ill gone mad if i suggest we try anything. but honestly? i kinda want to see what itd be like to give up control and act all little again for him. he says hes willing if its something i wanna explore too so... wtf am i doing. im still trying to figure out how i feel about all this adult stuff.
