Sense of proportion time?
I count myself as a reasonably keen rider. In winter I ride maybe 2 or 3 evenings a week, and some weekends. In summer, I often ride almost every day. Rides of 2 - 3 hours are common. I know others out there do more. And I doubt that the time I spend sitting in the saddle is more than 2 hours a week, spread in lots of short bursts between standing up, falling off, remounting, and all the other things that unicyclists do.
The bicyclists who get the dreaded penile numbness, and possibly lasting effects, are normally athletes who ride hundreds of miles a week and spend most of that time in the same position, on a narrow saddle with negligible padding.
I won’t belittle anybody’s fear of cancer (I have lost family to it), but we must accept that the fear is more prevalent than the disease - almost to the point of phobia in some sectors of society.
You can get long term medical problems including heart disease or cancer from a salty diet, a meat rich diet, too little exercise, too much exercise, working in a polluted city, driving with the heater on and the windows closed, working in an air conditioned building, living near power lines… the list goes on, and on.
Unicycling has many health benefits. It is good cardiovascular and aerobic exercise; it builds stamina; it is low impact (joking apart); it develops coordination and balance; it strengthens muscles and therefore bones, there must be a knock on effect in psychological health… and this list goes on and on too.
You can live or you can not die. They are two different things.
Enjoy your riding, and if it starts to hurt, back off for a bit, and build back up again.
