I could be faithfully monogamous with one woman and have done so for over 17years counting dating.  I know most guys often think with the wrong head, what separates mr right from mr wrong is the ones who don't act on those fatal impulses.  To take things one step further, I do believe that the ones who do cheat are most likely to repeat the offense (just ask my stbx!)

Well, here are the statistics...

According to Peggy Vaughan, author of The Monogamy Myth, first published in 1989 by Newmarket Press (third edition published 2003), conservative infidelity statistics estimate that “60 percent of men and 40 percent of women will have an extramarital affair. These figures are even more significant when we consider the total number of marriages involved, since it's unlikely that all the men and women having affairs happen to be married to each other. If even half of the women having affairs (or 20 percent) are married to men not included in the 60 percent having affairs, then at least one partner will have an affair in approximately 80 percent of all marriages. With this many marriages affected, it's unreasonable to think affairs are due only to the failures and shortcomings of individual husbands or wives."

In other words, it's a societal problem that's going to take somebody smarter than me to figure out how to solve it....
