unsuspiciousness

No, her's is not a cruel nature. I do not consider her as meaning to wound my feelings. The evil lies yet deeper; in her total ignorance, unsuspiciousness of there being such feelings, in a perversion of mind which made it natural to her to treat the subject as she did.

A mother is always more familiar with her son than a father is with his daughter, in the direction of any conditions that may grow out of their respective sexualities. Owing to this, masturbation is practised with much more unsuspiciousness by girls than by boys, especially at or about the time of puberty.
