I know this numb and uninteresting feeling from after I climaxed as a man, but I don't know if women can have similar feelings directly after the climax. If so, could it be that the orgasm was so small that you didn't register it??
It is curious that you write this in the chastity bra topic: do you feel that if you can have an orgasm like that, you will need a chastity bra as well for your goal of keeping yourself pure??
My guess is that it would not be wise to share this experience with your mother unless you are absolutely sure you 'deserve' one!
