Sexual activityA personal lubricant can be used to increase pleasure and reduce pain during sexual intercourse or other activities and may be used for lubricating the penis, vagina, anus or dildo or other sex toy before or during activity. Lubricant may be applied to any body part desired, to the inside and/or outside of condoms, or to the hands or fingers. Personal lubricants are particularly useful for intercourse when a partner experiences dryness or excessive contraction (tightness) of the vagina or anus. Anal sex generally requires more generous application of lubricant since the anus does not have natural lubrication sufficient for most sexual activity.
MedicineIn medicine, lubricants can be used for gynecological examinations, digital rectal examinations, the insertion of catheters, and the use of enema nozzles and rectal thermometers. The class of lubricants now known as "personal" derives from surgical lubricants; K-Y Jelly was originally introduced in 1904 for this purpose.
There are specific lubricants which may be used in male masturbation but are not suitable for vaginal or anal use or for use with condoms.Lubricant that is safe for sexual intercourse is also safe for masturbation.
