I was hoping to get some serious answers on this given the scientific nature of these forums. Please let's put the jokes aside and try and understand this issue. Is it not strange that there are at least a billions of men throughout time who have masturbated presumably in many different positions. Why is it that none of them have ever sat on the edge of a sofa and masturbated (or received oral favours on the edge of the sofa) thereby ripping their pelvic floor?

Unless you can point to a source that says that it has happened, or explains why it could happen, we have nothing to go on other than humor...
That will only give you anecdotal evidence which will in all likelihood be unreliable. So how do you intend to verify your sources?
Got to start somewhere. If even 10 people reply and all of them have masturbated safely in this position then there is evidence to suggest that it is not inevitably dangerous.

If even 10 people reply and all of them have masturbated safely in this position then there is evidence to suggest that it is not inevitably dangerous. On the contrary. Allow me to present an expert opinion. I will work through an introduction to clinical trial planning, using published statistics. Suppose we run the experiment for a week. There are 25,000,000 men in the UK, of whom 90% will not admit to having to resort to this procedure at least once a week ("don't be silly, my wife/girlfriend/boyfriend/butler sees to that sort of thing"). Of 2,500,000, 75% live at home with mum or in shared digs and therefore do not do it on the settee.Of 625,000 men who might do it on a settee, perhaps 10% will have one with a significantly rigid edge.Of 62,500 men who might masturbate on the edge of a rigid settee, 80% will be interrupted by the phone/doorbell/kettle/something better on TV/falling asleep.Half of the remaining 12,500 will suffer from premature ejaculation, failure to ejaculate, or erectile dysfunctionThe probability of recruiting volunteers from the remaining 6,250 is about 10%, assuming you can get saturation coverage of newspapers and television. I think there's a joke in there somewhere, but let's keep a straight face for a moment....We usually expect a 50% dropout rate from a volunteer panel if there is no financial incentive to complete the task, leaving about 312 active participants Unless you are prepared to interview every active participant (and you won't know who they are, because they will be randomly distributed among the 25,000,000 population) you can expect a 10% return of postal questionnaires - about 32.So if you get 10 reported survivors from a one-week national survey, you will have killed at least 20 of those who would have completed the task and survey but died in the service of science. That would not be considered by any ethics committee to be an adequate demonstration of safety. The European Union's overriding ethical principle is "precautionary", and this must be applied by controlled escalation, so as I said earlier, do it yourself fiorst. Our a priori estimate, as shown above, is of 75% fatality, so if you survive three sessions you would be justified in revising the risk and escalating to a Phase 1 "in house" trial with a panel of paid "professional" subjects with adequately informed consent. With less than 10% fatalities in the trial group you could then extend to say 1000 desperate men whose life expectancy has been compromised by inadequate masturbation: this is called a Phase 2 trial for which the ethics committee would demand accurate specifications and measurements and a commitment to publish your results. Things get more complicated if you want to conduct the trial in the USA. It's a tempting idea because from what we know of gun crime and the popularity of Donald Trump, there are many more lonely wnakers in the States than in the UK. But the Food and Drugs Administration demands not merely proof of safety, but "superiority". And here you have a real problem. What, on God's green earth, can masturbating on the edge of a hard sofa, be superior to?
If the answer was a simple yes or no, you would have found it by now from the internet or a textbook. Clearly the reason you have posed the question on a science forum is because you aren't satisfied with the textbook answer, or there isn't one. And that's why we have qualified doctors and scientists on hand to help you conduct and evaluate an experiment.
The answer to both my questions are a simply yes or no. Take you for example, if you are unable to answer yes or no to1. Have you ever sat on the edge of a sofa and ejaculated?2. Did you injure your pelvic floor whilst ejaculating?Then you are either mentally ill, possess an incredibly short memory, or you are being purposely facetious.
