In sexual life, the technique of penile thrusting is very important for men to help women reach orgasm easily. Besides the duration of sexual activity, the frequency and depth of the man's penile thrusting are highly related to the sexual pleasure experienced by both partners. Practical experience shows that the higher the frequency of penile thrusting, the more chances the penis and vagina will make contact within a unit of time, allowing the sexual center to receive more information within that time, making it easier to stimulate sexual pleasure responses.
