Since so few individuals were involved in sexual activity with animals in any period of life, frequencies can be calculated for only a few groups and for only two periods of time: puberty to age fifteen and ages sixteen to twenty.
The frequencies are, as one would expect, low. However, if one considers only those individuals with animal contact and calculates the frequency for them alone, the resultant figures range from about 4 to 20 times per year for the average (median) persons of the various groups. The mean frequencies are, of course, higher, ranging from once a month to nearly once a week.
Examination of these frequencies raises more questions than it answers. Frequency not only bears no relationship to rurality but none to incidence either. In fact, the control group—which had the lowest incidence of animal contact—exhibits the highest frequencies in every instance but one: it is surpassed only by the heterosexual offenders vs. adults who had the second lowest incidence. The high frequencies of the control group proved to be due to the presence of a small but unusually active minority of about ten men.
