Ive seen previous responses, and there are a couple of adequate
solutions.  However, I would recommend questioning seriously why
you don't want to have Human as a generalisation of Man and of Woman.
After all, Man Is-A Human, and Woman Is-A Human, and the
generalisation relationship is one that implements Is-A relationships.
