I think it’s a bottled up desire that stays buried for too long and also what helps to bring it out is the problematic dilemma of meeting women and getting them to have sex.
Nowadays, older women want to feel young and they cater to a younger man who fulfills their own desires. They don’t view sex the same way men do.
With a man, we are easy to find, cut through the bullshit and understand it’s just pleasure without attachment. We are able to switch into pleasure mode, then walk away and resume our normal lives.
I believe at an older age, men might view pleasure from sexual activity as simply as a task. They enjoy the task, but when they get horny, they just want to get off and move on. Other men help to accomplish this efficiently.
