<unk>  has high prevalence rates in most studied populations.<unk>  was initially believed to only be present in a small portion of the population. This perception changed when Alfred Kinsey discovered that 30% of men prefer coitus with the lights on. This behaviour is not considered<unk>  by today's diagnostic standards, but there was little differentiation between normal and pathological behaviour at the time. Subsequent research showed that 65% of men had engaged in peeping, which suggests that this behaviour is widely spread throughout the population. Congruent with this, research found<unk>  to be the most common sexual law-breaking behaviour in both clinical and general populations. In the same study it was found that 42% of college males who had never been convicted of a crime had watched others in sexual situations. An earlier study indicates that 54% of men have<unk> ic fantasies, and that 42% have tried<unk> . In a national study of Sweden it was found that 7.7% of the population (both men and women) had engaged in<unk>  at some point. It is also believed that<unk>  occurs up to 150 times more frequently than police reports indicate. This same study also indicates that there are high levels of co-occurrence between<unk>  and exhibitionism, finding that 63% of voyeurs also report exhibitionist behaviour.
