Kay's handbook combines the usual information on reproductive organs, fertilization, fetal development and the physical changes of puberty with a cautionary lecture in which the threat of pregnancy (or correspondingly, a paternity suit) constitutes the chief message. Intercourse is an expression of adult love, desire and ""other feelings which include a willingness to accept the responsibility of caring for a child."" The main thing about birth control methods is that they don't work all the time, so, ""Naturally, the next question is what do you do instead"" and the answer: ""Stop, now."" Pregnancy is possible even if you ""fool around"" without going all the way, and abortion, which is not mentioned in a discussion of possible responses to pregnancy, is dismissed later as ""dangerous even under the most perfect conditions"" and illegal in many states while allowed only under health-threatening conditions in others. This approach provides neither the information on which adolescents can base their own unconstrained decisions, any consideration of other arguments against early intercourse, nor a fraction of the practical guidance contained in Lieberman and Peck's Sex and Birth Control (KR, p. 649, J-225).
