Pink sock refers to the protruding of the prolapsed anorectal tissue as a result of excessively forceful anal sex. A part of the rectal tissue dangles out and looks like a pink sock. It is an abnormal and extreme medical condition that needs immediate attention if it happens. Many cases of the pink sock have resulted in death.
More About Pink Sock
Anal intercourse requires the receiving partner to be properly lubricated. The anus does not lubricate naturally. For penetration and intercourse to be comfortable, a sex lube is required. This lessens the risks of rectal lacerations and, in extreme cases, the pink sock. Reapply the sex lubricant as needed for continued comfort.
