Google the term
male gaze.
We women are pretty constantly bombarded with the message that we have a short shelf life. That our value is below the waist only. And that any deviation from social norms related to attractiveness (think stuff like not shaving armpits or having tattoos or dressing overly conservatively—or overly liberally, for that matter) is cause for shunning, ignoring, and belittling.
It can manifest itself in all sorts of ways, including not getting a job or a mortgage or the like. Yeah, it's discrimination. But people shrug it off as being,
well, that's gross. Why doesn't she shave? Etc.
How often do you see significant age gap relationships? I mean over 5 years' difference and more like 20. Who, inevitably, is the older and more powerful person? If you said the one with the penis, then you would be right.
In your age bracket, and in my Dad's (he's ~ 5 years older than you), there are about 38 men for every 100 women, according to the
US Census. But you would think that this ratio held true in our 50s and 60s with the large number of men who specifically in their online dating profiles don't want a woman over the age of around 30.
Don't believe me? Then check out
research which asked men in 45 countries what age woman they preferred. Big shocker there—a majority preferred younger women (although in all fairness a lot of these men preferred women within 5 years of their own age).
Look at media, too. Check out Hollywood's perception of a healthy age gap and you'll often see a huge gap in real life. And this can often be the case in stories where that gap isn't a plot point at all. Consider the film
Six Days, Seven Nights, which pairs up Anne Heche and Harrison Ford. Heche was born in 1969. Ford? He was born in 1942.
That's almost as much of gap as in his real-life marriage. His wife, Calista Flockhart, was born in 1964.
This is just one example and you can find tons of them online.
