The political correctness of the whole issue is a total joke , and now of course everybody must be careful not to offend , how lovely .
Well some may wish to deny sexual attraction and live within the moral high ground , but the fact of the matter is all begins with sexual attraction ... you may well get bored and form a closer mental link , In this case you may remain faithful because 1. You have no other options 2. You would not feel happy about " cheating " on your beloved 3.You are just too OLD and its all just too difficult .
You hit the comfortable middle ground , nothing wrong with that , but we love to try and fight the fact ..that men are men and women are women .
If you really were not concerned about convenience , and maybe your kids ( dependent on age ) ..Whats the actual answer ? ..
Im not sure , but men and women are extremely different and Its all driven by Sex and attraction .
