I agree, Gyno-X was great and probably the best medical fetish site so far. While indeed most models were rather passive, but one could tell a few of them kind of enjoyed. Some even found it funny...
I heard there was a connection between "GynoFetishDreams" (a very old site, disappeared a long time ago but there are a few intriguing videos) and Gyno-X. It seems that at some point they split and the "ExclusiveClub" emerged from it. At least this is what I assume, because the old guy from ExclusiveClub showed up in some old Gyno-X pictures. Somehow both sites merged again into GynoExclusive, but unfortunately it is super close to the ExclusiveClub style of videos.
I'm not sure why they stopped making videos, but I assume that it got harder to find and pay models. Nowadays, these sites have to compete with so many more porn sources that - at least this is what I believe - it is not economical to run such a site. It probably also is what is happening to GirlsGoneGyno (they were at three videos per week, now only one). Does anybody know who actually operated that site?
About their injections: As I'm not into injections, I cannot really judge that, but I still appreciate that they included them and had someone knowledgeable do them (yes, the old nurse). They also varied with the positions when the girls got the injection, some even got dressed and had to drop their pants again for them. I do appreciate this variety. Unfortunately, they never really gave a dialogue about anything. It would have been nice to hear why the girl gets an injection. Also, sometimes not just some Vitamin B but some small isotonic solution or another vitamin?
