It's more that "men" (around under 40) have become A LOT more soft. Not all their fault, it's a combination of lower testosterone genetically, over-parenting, and what they were taught in school.
This, in combination with female empowerment, #metoo, and all the attention they get from social media and dating apps, has created the PERFECT STORM.
I have huge success dating women 20-25 years younger because I keep in great shape and exude confidence and own a business. Their DNA wiring says "mate with this guy" and that's something they can't turn off. I have se*x with maybe 30-50% of them.
One thing that has really worked in my favor are dating apps where mature men can find younger women to hang out with. The whole age difference issue has become much less taboo is the past 5-10 years.
