The cheapie American tabloid National Informer warns on this cover from today in 1968 that too much sex can drive you insane. We would think the opposite is true, but the article quotes the eminent (or perhaps entirely fictional) Dr. Frans Hersen, head of the renowned (or fictional) American Sex Institute: We visited mental hospitals looking for sex problems related to a totally different study and suddenly noticed that many of the cases in the various institutions were all related to TOO MUCH SEX (emphasis theirs). So there you go—the science is clear. We have plenty more National Bulletin tucked away inside Pulp Intl. and you can see those by starting here.
