Normal? Who's normal?

Okay.
I once read an article in some magazine or something.
It said that the people you are sexually attracted to are a result of images that you were exposed to at the age of around seven. Seven is apparently the age when we start to become sexually aware.
The main body of evidence for this was that there are a large number of gas-mask fetishists among British people who grew up during the war, yet not many in America, where gas-masks were not issued so much at that time.
Sounds crazy.
But I am thinking there may be some truth in it.
You see, when I was about seven, my Mum used to buy this magazine called "Women's Own" , and I sometimes used to look at it.
There was an advert in it for a sort of a healthy fruit drink, called PLJ.
The advert featured a naked woman bending backwards with her arms above her head, in kind of a gymnast pose.
There was nothing pornographic or erotic about it, but she was naked, and I had never seen a naked woman before. It was fascinating to me.
The woman in the advert was of a fairly average build and she had quite small breasts.
I have always found that the women I find most attractive are of average build with quite small breasts.
So maybe there's something in it. If my Dad had read the Sun, I might be more attracted to busty blondes.
Can it really be that you will take someone to have and to hold, in sickness and in health, until the day that you die, because they look similar to a photo you saw in a magazine when you were seven?
