I don’t feel old, look old or have degenerative medical issues. I will bet that I can out cycle and out run you by miles.
The idea that it’s perverted for me to have consensual sex with someone 25 years younger than me? social acceptance by the younger person’s family and social circle can weigh heavily.
But when my daughters dated guys older than them, my main concern wasn’t their age, it was if they were a jerk!
And without question, the biggest Jerks were those younger guys who felt they were universally powerful and immortal, lacking compassion and respect. When I was young I had friends who were much older than me, because I quickly outgrew peers my own age.
Finally, I can see how the 8 year average [age difference in a marriage] makes sense for average people. If someone truly looks and behaves 10 years younger, then you can add those 10 years to the 8 for 18.
