Pornography and Sex Crimes
Much of the controversy surrounding pornography is related to society's concern about how pornography affects people. One common worry is that the use of pornography promotes sex crimes and that sex offenders are avid consumers of obscene material.

Research, however, does not show any consistent pattern. Data from studies conducted in the 1970s and 1980s have consistently shown that the use of pornography is not related to an increase in sex crimes and that sex offenders in general have had significantly less exposure to pornography than non-offenders. Some later work in this area has not agreed with these earlier findings.

Another popular belief is that only perverted individuals would be interested in pornography. Findings from the historic Kinsey study showed that between 14 and 60 percent of females and between 36 and 77 percent of males were stimulated by viewing sexy movies, reading and hearing erotic stories, and viewing pictures, drawings or other portrayals of sexual activity. The Redbook survey (1974) reported that 60 percent of the 100,000 married women they surveyed had seen a pornographic movie, and 42 percent of these women had used pornography in their sexual practices at least occasionally.

When the magazine Psychology Today asked 20,000 readers whether they had ever used erotic material for arousal, 92 percent of the male respondents and 72 percent of the females reported that they had.

Pornography Materials Widely Used
In 1970, the U.S. Commission on Obscenity and Pornography conducted one of the few scientific interviews of adults in the U.S. regarding pornography. Eighty-four percent of the men and 69 percent of the women indicated that they had used such material at some time.

Finally, the tremendous popularity of magazines such as Playboy, Penthouse and Hustler provides undeniable testimony to the widespread use of erotica.

Furthermore, the U.S. Commission on Obscenity and Pornography reported that ordinary people did not change their types of sexual practice or values about what was acceptable as a result of viewing pornography.

It also reported that there was a general increase in sexual activity within the 24-hour period after viewing pornography, but it was generally with the regular partner, or in the case of those without a partner, masturbation.

It is noteworthy, however, that neither the Commission nor the authors of the other studies observed the effects of continuing exposure to pornography over a period of years. Thus it is not known what, if any, differences would be evidenced in the long run.
