Its hard to believe that women produce about 400 eggs in a lifetime. Women are also only able to produce one offspring at a time. In addition they are afraid of that biological clock. Now us guys, we can expel upward of 100 million sperm each time we ejaculate. Like our ancient pharaohs, we have the potential to sire hundreds, even thousands of kids during a lifetime. We've been genetically coded to cast our seed as far and wide as possible and to pledged allegiance to the flag of Wham-Bam-Thank-You-Ma'am. Think about it women, how can you expect us guys to commit, why should we put all our hopes and future generations on just one women. This idea clashes violently with the deeply embedded imperatives of our species survival. I am not saying this to justify my rampant love-em-leave-em behavior, lets just put the blame on genetics.
