Question

________ is the stimulation of one's own genitals for sexual pleasure a. mutual masturbation b. masturbation c. coitus d. fellatio e. cunnilingis

Answer 1

B. Masturbation.

Step-by-step explanation:

Mutual masturbation occurs when two people masturbate together with consent.

Coitus is sexual intercourse, so two people are needed and doesn't count as masturbation per se.

Fellatio is oral stimulation of one's penis.

Cunnilingis is oral stimulation of a female's vagina.

Hope this helps :)
