A quick google would reveal that at least 15-20 universities have had "sex week" type programs. Three of them on the list I found were Ivies, of the possible 8 schools. Others included state universities such as Universities of Maryland, Tennessee, Kentucky, Michigan and Minnesota. I wonder if all schools in the SEC, Big 10, etc. are detrimental?
In regards to professors with views well outside what one might consider the more mainstream, the Ivy hardly has that market cornered in higher education.
