If you think men prefer to ogle silicone over flesh, you spend too much time watching TV and not enough time with men.
Nudie women magazines fly off the shelves a lot faster than nudie men ones.
First, nudie mags aren't actually that popular. Playboy is the best-seller at some 3 million copies. There are a hundred million men in the country; most men see one only rarely. The pornography tail shouldn't be wagging the female psychology dog.
Second, your example works both ways: as you say, magazines full of muscle-bound men with large genitals don't sell very well (particularly not to women), yet most men believe that's what women want nevertheless.
You can say, "well, women are right and men are wrong", but any woman who falls back on that should just go and get a boob job.
Not my point.
I said they ogle breasts whether silicone or not as it's not apparent initially what's fake and what's not.
Thus, it's not just that women think men OUGHT to want bigger breasts as you said...the lust of most male eyes makes it logical for women to assume this is a turn on for men.
There are way more men tempted by pornography than women. Your point there just won't fly.
