Age psychology of male love

A twenty-year-old boy and a man of 35+ are in love. What is the difference?

On the one hand, the question is banal, since the difference is obvious: "puppy" enthusiasm / passion of the mature; lack of experience / experience; lack of control / self-control. And yet ... if closer to the feeling, to the spirit. And even with the fact that some small part of "ME" does not grow up. I do not know how much this corresponds to scientific psychology, but, according to my observations, from about the age of 14 (plus or minus) a person looks at himself as the current one. Those. before that I look at myself as if I were a child. And from the time of an adolescent / youth I consider myself a Name. I can notice the age changes in myself (I was an idiot if I did not notice them, but I do not identify myself ... I'm not changing anymore ...

Let's return to the topic (I wanted to write, to our sheep, but erased - the theme after all about men, and polorogie us are not interested). As the age changes in a man are combined with a certain constant component, with self-identification of himself as Ivan Ivanov, different not only from other men, but also all people in the world. In the end, you can truly love, in my opinion, even in 10 years ...

I would like to hear something personal, lived (and from women, by the way, too), can be a little veiled / generalized / abstract, so as not to slip into "digging in someone else's underwear." In short, we need a variety of opinions for the cause, not just our own.

Thanks in advance, who will be able to state. (Links to good articles are also welcome).
