Eve was not named until after the fall (Genesis 3:20) at which Adam claimed dominion over her. Adam and Eve were of one flesh (Genesis 2:24) so the sin was shared equally. Just as it is a linguist convention to refer to all of humanity as man or mankind so was it when St. Paul was humanity that caused sin to enter the world. Were this not so death would not have spread to women, but only to all men (Romans 5:12).
