We all know that swingers come in all different shapes, sizes and colours, but the one factor that many people seem to have the least amount of tolerance for is age. If a "Australian mature swingers" has set an upper limit then they very rarely consider meeting people above that age bracket, even if an older couple is quite easily more attractive and in better condition than those much younger.
The preconceived assumption is that people of a certain age are too old regardless. Is there anything really that weird about shagging people ten or Australian mature swingers years older than you? It would seems so with most couples firmly keeping their sights below fifty regardless. In spite of that mentality, a good percentage of swinging couples "Australian mature swingers" over the age of fifty and they are having a ball.
If anything, they are having way more fun than the younger, self-conscious set. After more than a certain number of decades on this planet, you stop caring about what other people think.
In term of swinging, this is actually a fantastic mindset. A lot of people take swinging too personally and allow themselves to get caught up in worrying about how they are perceived.
