The question whether the sex play was heterosexual is our next concern. In compiling a rank-order of those who ever took part in heterosexual play, it again becomes obvious that the percentages involved are influenced by the average age at puberty, although not so strongly as was true for prepubertal sex play as a whole. The agreement between incidence of heterosexual play and age at puberty is rather good except that the homosexual offenders show more moderate figures despite their early puberty (their homosexuality seems to compete with heterosexuality), and two aggressor groups have larger incidence figures than their age at puberty would make one anticipate. We see that relatively few of the heterosexual (including incest) offenders against females aged twelve and over had prepubertal heterosexual play: they occupy the lower portion of the rank-order. These groups were relatively late in reaching puberty. The control and prison groups are 52 and 53 per cent, i.e., centrally located in the rank-order. The offenders against female children under twelve, the homosexual offenders, and most of die heterosexual aggressors rank higher than the control group. The first three positions are filled by groups whose members reached puberty early. However, fourth place is occupied by heterosexual aggressors vs. adults who reached puberty rather late; this, plus the fact that the heterosexual aggressors vs. minors head the rank-order, makes one feel that aggressiveness per se may be associated with prepubertal heterosexuality.
In homosexual play the three homosexual-offender groups occupy the first three ranks with percentages of from 60 to 69. Once again the control group is rather central (41 per cent), and the heterosexual offenders (including incest) against females aged twelve and older occupy the lower portion of the rank-order. Two of the heterosexual-aggressor groups are low in homosexual play whereas they were central to high rated by heterosexual play. We shall see that this is probably the result of the aggressors being more strongly oriented toward prepubertal heterosexuality than most of the other groups. The prison group, which was close to the control group in measurements of the presence or absence of prepubertal sex play and in heterosexual play, exceeds the control group in the proportion of members who had homosexual play. This is our first intimation that throughout life, pre- or postpubertal, the prison group is more homo-sexually inclined than the control group, an inclination subsequently reinforced by imprisonment. The correlation between incidence and age at puberty again exists as it did with heterosexual play (see Table 20).
Having examined the simple presence or absence of prepubertal hetero- and homosexual play, it is worthwhile to see how many individuals with sex play were exclusively heterosexual or homosexual in their sexual activity.
With regard to exclusive heterosexuality, all of those whose sex offenses were against female children are in the upper portion of the rank-order with percentages of from 25 to 36. Similarly, the heterosexual aggressors rank rather high, occupying second, third, and fourth ranks. The control group is once more centrally located with 23 per cent. The homosexual offenders occupy the bottom ranks.
Exclusively homosexual play is somewhat less common. First through third ranks are occupied by the homosexual-offender groups (20-24 per cent), the prison group is more or less central, and die control group is a bit low. Again revealing their prepubertal heterosexual orientation, two of the three heterosexual-aggressor groups occupy the lowest two ranks.
Since one lone experience suffices to place a person in a category such as “exclusively heterosexual play,” we had to get an idea of the quantity and intensity of the sex play in some other way. We therefore calculated the duration of sex play and the techniques involved.
