How exactly does a father feel about his son (say 17 years of age) bringing home a girlfriend (approx. 16/17) and having sex with her under his roof with him being home or not. Women usually have a very different view on this. If my daughter ever did have sex at that age in my house, then I was not aware of it or just plain stupid. What is a man's perspective on these issues? Some families do not allow boys into their daughters' rooms but girls are allowed into the boys' room. I don't understand the difference. To me it is my child and a certain set of rules apply, whether it be a son or a daughter.
