I also initially found the "medical gay porn" fetish silly back in 2008 when I first joined this site. But a very wise man, (whose writing style is somewhat similar to yours TG), named Slimvintage pointed out that the medical fetish is like other fetishes, very specific, and the fans of it NEED to see what I find tedious and repetitive, from the weighing and measuring and coughing, etc. He pointed out that the ritual of the examination that leads to the naked patients and then the sex, is the necessary key to getting the medical fetishist off.
David and Eddie who were the original producers of
Broke Straight Boys, still do the
College Boy Physicals scenes, and David explained to us that he was sexually attracted to his own physician when he was growing up, and that is when he began to get excited by the prospects of doctor patient sex.
It is not my fetish, and I only look at the scenes when one of the forumites mentions a particular scene that sounds like it might tickle my fancy. But I almost always fast forward through what I find tedious in the examination, to get to the "meat" of the matter, so to speak. But for the true aficionado of the genre, the exam is MOST important to lead to the hot sex.
