That male is probably being driven by the same desire to pass on his genes as most of us experience as simple mammal males. Although the male is insistent in his desire to mate with the female, we must remember that he is driven by much the same thing that drives many of us common livebearer males, even us mammal type. If I cannot mate with success with a female, she gives me no drive to reproduce with her, but if I have a chance of having my genes carry on with the next generation, I have a significant incentive to continue to mate with that female. In my point of view, there is no "wicked way" of chasing a particular female. Instead there is the desire on the part of the male to improve the chances that his own genetic contribution will be passed on to a female. Although the chance of passing on his genes is a significant factor, the male has no way of knowing whether or not his attentions will result in an increase of the chance of his own genes being passed on to the next generation.
