Playboy is available for everyone at my library in Zürich (the very reputable Museumsgesellschaft) in the general reading room (no age restriction for access) - and I have noticed male/female members looking at it without any attempt to hide.

The Kinsey report is also generally available (you don't have to ask for it, but it is for reading/studying inside the libraries only) at the general reading rooms, both at the above mentioned library and at the library of my Alma Mater (Hochschule/University of St.Gallen).
