Is it normal for men in their late forties and fifties wanting you to talk dirty to them and go see porno movies when they did not when they were younger?

As a man ages, he needs more stimulation to become aroused. At some point, a man will lose his ability to have psychogenic erections, meaning that he gets an erection just by thinking an erotic thought. At that point he will require physical stimulation, having his penis touched in some pleasurable manner, in order to obtain an erection. But before he gets to that point, he might feel he needs a psychological boost to get a psychogenic erections, which could take the form of talking dirty or seeing erotic images. That these physical changes occur is absolutely the norm. How a man deals with them is going to be different on a case by case basis so there is no “norm.” If the particular ways that your man has of dealing with this bothers you, you could talk about it and see if there weren’t other solutions that you would find more appealing. For example, some women find talking dirty is a distraction to their own ability to become aroused, so that certainly is not a good solution. So the idea is to find a way of getting your man aroused that you’ll both enjoy. And don’t look at this as a chore, but instead have fun exploring different ways of turning each other on.
