What things sexual/physical do you learn about yourself as a 40+ man

I agree with @WillaimG. The older I get, the more I love getting my partner off. I have become a total man pleaser and absolutely get into pleasing men totally. Also, even though a big dick is always a plus, size don't matter as much as it used to, it's damn fine sex and giving a guy a mind-blowing nut, large or smaller dick. Good intense sex is worth a lot more than dick size.
