Because of the internet, social media, porn, etc. women are going to see tons of men that are ripped/fit and/or have a large penis, so it's not all that impressive to them.
You have a good point here, but it's not all the internet's fault. In the 1970s-early 1990s, there were plenty of magazines, mainstream movies, and porn movies with ripped/fit guys and guys with large penises. There wasn't a need for the internet for that, but it has made it more accessible. High speed, broadband internet is more important than internet itself because streaming porn videos wasn't easy in the dial-up internet era. The early 2000s is about when broadband became more common than dial-up.
A guy that is 7"+ is in the top 5% of men, which is well above average, but because women see pictures of something like that all over the internet it's not unusual for them.
A 7 inch penis is impressive in the real world. In porn, it would be a smaller penis, as most porn star penises are 8"+.
In the pre-internet era, porn star penises were big too, but porn wasn't as easily available. A woman would have to go to a porno shop to get VHS or DVD porn videos and magazines. That's a different experience than sitting at home on a broadband internet connection and visiting a website with more free porn than one could consume in a lifetime.
I've been doing no porn and no fap for a bit, and it was extremely difficult to stop internet porn and fapping.
Men do watch more porn than women, but women have been watching more porn in the last 10-20 years.
Women have been aware of porn for many decades even if they haven't been the biggest consumers of it. Regular women have been copying porn stars with pubic hair maintenance and often getting breast implants.
When a woman sees a bunch of huge penises on her laptop or even mobile phone, it does raise her expectations and she does become more entitled.
This also applies to a man's physique, women will see tons of photos of fit/jacked men, many of whom are either on steroids or the photos are incredibly edited, and they aren't as impressed by a legitimately fit man. Again, all of this is because they've become desensitized to seeing this due to the internet.
With seeing men with big muscles (not in porn), women are seeing more of it with the internet too. There are more men with big muscles/fit on social media. Pre-internet, she would have needed to buy muscle and fitness magazines to see tons of ripped dudes.
