So someone help fill me in here. I'm horribly ignorant about this...

If it is instinctive for species to mate and the does are 'in the mood' so to speak with their hormones, then why does all the chasing have to happen? Why are the does running around or running away? Are they truly afraid of the bucks? Is the mating process uncomfortable? or are they truly playing 'hard to get'?

I'm just thinking of my 16 year old boy and his new found interest in girls and their 'body parts'. I'm finding that the human 'does' are just as interested in the human 'bucks'. It seems the human hormones turn off any rational thought and the two sexes run together not away from each other!!
