Are women with more sensitive fingers more likely to masturbate?
In a sample of 97 healthy Dutch female university students, women with greater finger tactile sensitivity (von Frey-type filaments) engaged more in partnered (but not solitary masturbation) sexual behavior. Orgasmic responses in the past 30 days were not correlated with finger sensitivity. Results are discussed in terms of differences between different sexual behaviors, as well as susceptibility to reinforcement, and psychoanalytic views of conversion hysteria.
