Is there anything wrong with asking your mother to choose one of her close and retired friends as the person who will take your virginity?
Whether it is right or wrong does not really apply. But asking
whether it is appropriate would be a better choice. There are
cultures where this type of behavior is common place, but in our
modern Western culture it is not. So, the best advice would be to
not involve your mother or any of her friends, retired or
otherwise, in your personal intimate life.
