Soaking (sexual practice)
Soaking is a sexual practice of inserting the penis into the vagina but not subsequently thrusting or ejaculating, reportedly used by some Mormons, also known as members of the Church of Jesus Christ of Latter-day Saints (LDS Church). Soaking is reportedly used as a loophole to the LDS Church's strict rules against premarital sex.
