Of course it's wrong, and i can't condone tricking & misleading guys into thinking he's a doctor doing a study, while intending to exploit them.
But i can understand it. Doing so allowed the physicals to appear realistic, and not some fake cheap porn. Tricking them was necessary to get a better quality video effect. He needed them to feel like patients so that they would realistically act like patients. And i guess it helped get guys to participate who otherwise would not have. That provided a better pooling of guys to be patients, vs clowns that don't mind being nude and showing off.
So i get it. It's totally unethical, and just wrong on so many levels. Think if you trusted someone who you thought was a discreet professional, and the next thing you know, your nude body is being shown all over, perhaps in an embarrassing circumstance you'd rather no one would ever see.
Then I get to thinking about the guys on this thread, and the many others not on this thread who share the same sentiment. It seems this was a hot concept to have. I'm sure those who lament that it's now over would like to see someone else start up something similar, though with proper to the subjects who would participate. Whether a health care professional actually wanted to do a real study that would produce similar kinds of videos, or if the production could be done more realistically & believable than, say, the college boy physicals videos, etc.
if there were enough interest, and enough guys from this site or a connection established to get participants within a reasonable proximity to each other, I think you could get someone to play a believable doctor, and a bunch of guys may want to be patients. I know I've chatted with guys on here who would like to have their play exams filmed. A concept like this could bring that to another level for them.
