Not only do I OWN this book, I found about it during my first visit to the Library of Congress — where I READ it in the reading room.
My friend and I went in there and knowing we could probably get any book on any subject, I typed “masturbation” and this came up, so I put in a request slip. A while later, it showed up and I sat there at a polished desk reading it. It is VERY instructive! My friend went off for a couple of hours sightseeing while I read on. Years later I got a copy of it via American Book Exchange.
