Finally, she knows that she's an
unmarried
middle-aged woman with
no children, so she
can't defend herself by saying that she
has children, in order to say that there's
nothing wrong for her to have
lost her virginity.
This is probably why she keeps declaring that she's a "virgin", so as to
try to save her "face" by
stopping/preventing other people from thinking (even if she's
truly a virgin) that
because she has no children and no husband, she
must have had
non-marital sex
several times with
at least one or two men after her marriage with her ex-husband ended,
whenever she felt very horny!
