Do we need to start throwing out the stats for how many rapist are men compared to women?

Sure, just as long as you define rape in such a way that female-on-male rape actually counts as rape, which it doesn't in the vast majority of "rape statistics" that get put out. Quote http://time.com/3393442/cdc-rape-numbers :

And now the real surprise: when asked about experiences in the last 12 months, men reported being “made to penetrate”—either by physical force or due to intoxication—at virtually the same rates as women reported rape (both 1.1 percent in 2010, and 1.7 and 1.6 respectively in 2011). In other words, if being made to penetrate someone was counted as rape—and why shouldn’t it be?—then the headlines could have focused on a truly sensational CDC finding: that women rape men as often as men rape women.
