My family has a saying "Small/Large upside, Small/Large Downside". The point of which is to weigh the upside of a choice against it's downside.
It occurs to me, that given this issue, this analysis seems prudent. On one hand, we have the upside of creating a personal exam video. While this would probably be a significant upside to many people, it would occur to me that there might be other ways to achieve this, including searching the internet, visiting a play-practitioner, etc.
On the flip-side, the potential damage here seems overwhelming. The obvious factors are the risk of discovery by the medical practice, which could have consequences ranging from the loss of the opportunity to visit that particular doctor, to the potential of criminal prosecution and possibly even jail time. Then one also must consider that, in doing this, the medical professional becomes an un-willing, un-aware partner in your fetish activity. I certainly cannot speak for everyone, but in the shoes of a real-life doc (which I am not), I would personally be less than thrilled by a patient engaging in this practice. It just seems less than honorable to me, and perhaps even, to continue the use of the term by ladydocisin, creepy.
Every person must weigh those odds against each other for themselves, but I find it hard to imagine that the benefits here outweigh the risks and downsides..........the juice just isn't worth the squeeze.
