Ejaculation in older men.
It is very important for older men to understand that rush to orgasm is often problematic for them. It is just a function of men's evolving sexual function.
Erections come more slowly and are lost more easily during love making. This is natural.
It only becomes a problem for older men when they begin to compare themselves to what they were like when they were much younger. When they ask themselves, "Will I get it up?" or "Will I be able to cum this time?" it almost certainly interfers with their success.
I often tell older men to focus on slow sex as your comment in this article suggests. Make it about touch, massage, playfulness, FUN, and not a contest to reach some magical moment.
Of course ejaculations are pleasurable, but if you focus is entirely on that moment, you will miss a lot of the joy and pleasure of lovemaking.
