This pretty speculative and kind of sexist.

I mean you could kind of flip it around, only instead of men and porn it's women and dating apps.

That the likes of tinder makes the most attractive men far more accessible to women, so they are no longer interested in the average man.

And similarly tinder apps and the like have drastically reduced the costs of dating compared to the past. It's private, you only get hit on by men you like. You can safely reject them etc...

I think this is just as inflammatory.

Are men really choosing turning away from women because they are "lame" compared to porn? At least for me porn is for when I'm not in a relationship or my s.o is occupied.

If I had to reach for a cause I would say it's a mix of economics and modern entertainment/past times being far less a social experience.

I was in rural village recently and it was pretty clear to me that people are going to hook up less if they are spending their weekends on Facebook and Netflix then dancing around a fire.
