Dont' know what department is running the study, but my package was postmarked from a doctor, which helped set me at ease. I was not aware that IU had the kinsey institute and that is a bit intriguing.

I also discovered that They fit while MUCH thinner and more comfortable are not necessarily perfect for me as I am thinner at the base than the middle and they don't taper as much. I think this is only an issue if I'm drunk and not completely hard...
