Who on Earth comes up with these ideas? I'm 48 and I've never gone though life looking at women as sex objects and unconsciously selecting them as mothers of my children. I've never had children and I'm happy enough I didn't. What's always mattered to me is whether I can spend an evening with someone and not get frustrated or bored. I would soon tire of a good-looking woman who only wanted to talk about what one of her friends said to another of her friends, then wanted to watch Eastenders and the X-Factor! She'd be out the door as quick as she liked, good looks and all!
I used to be a chauffeur and I heard thousands of conversations. I never really heard men talking about women in terms of sex or looks, nor did I really hear women discussing men that way. What I did hear all the time was real competition within the same sex. Many men try to compete with each other for status and establish a hierarchy by bragging about job, house, car, leisure activities etc.
Women were far worse about each other and I would even use the word 'nasty'. I might have four women in the car all chatting happily. As soon as one got out, the others would tear her apart over her hair, clothes, shoes etc. As soon as the next got out, the remaining two would tear her to pieces about the same things!
I think most of these ideas are contrived and don't really reflect reality.
