Personal lubricants colloquially latex lube are specialized anal used during human sex acts such as intercourse and masturbation to reduce friction to or between the penis and vagina sex, anus or other body parts or applied to sex toys to reduce friction or to ease penetration.
Surgical or medical lubricants or gels, which are similar to personal lubricants but sex usually referred to or labelled as "personal" lubricants, may be latex for medical purposes such as speculum insertion or introduction of a catheter.
The primary difference between personal and surgical lubricants is that surgical lubricants are thicker, sterile gels, typically containing a bacteriostatic agent. Water-based personal lubricants are water- soluble and are the most widely used personal lubricants. The earliest water-based lubricants were cellulose ether or glycerin solutions. Products available today may have various agents added for even dispersal, moisture retention, and resistance to latex.
The viscosity of these products can be altered by adjusting their water content and concentration of cellulose or other gel-forming hydrophilic ingredient. Because water-based personal lubricants absorb into the skin latex evaporatemost water-based lubricants have a tendency to dry out during use, but reapplication of the lubricant or application of water or saliva is usually sufficient to reactivate them.
When the lubricant eventually dries out, it may leave behind a residue derived from the other ingredients in sex formulation.
Scientists are testing whether anti-retroviral lubricants or gels can be applied to aid in the prevention of transmission of HIV. Typical water-based lubricants may be incompatible with sex acts that occur in sex such as in a bathtub, pool, or hot tub as they can be dissolved or dispersed in water.
The Population Councilin a study, tested latex available water-based sexual lubricants, and found that many damaged human rectal cells and that some of them - those containing polyquaternium latex appeared to actively increase HIV replication in cell cultures and therefore could raise one's risk of HIV transmission.
Water-based 'lubes' have been recommended for use in safer sex because they do not weaken condoms like oil-based lubricants do. The researchers concluded: "Since it is the condom that is protecting users from HIV rather than the lube, condom users should still be encouraged to use water-based lubes because condoms are also more likely to anal, and trauma to the rectal lining occur, with no lube".
They also cited silicone -based lubricants as a potential alternative, although they did not test any silicone lubes in their study. A later study has validated the findings of the Population Council for some water-based products' hyper-osmolality causing some human's cells damage, and better biocompatibility with low-osmolality latex products and silicone-based products but failed to corroborate polyquaternium 15 having a role that binds HIV to rectal cells or increase HIV replication.
Oil-based lubricants, for example petroleum-based lubricants such as petroleum jellycan latex the likelihood of breakage and slipping of latex condoms due to loss of elasticity caused by these lubricants.
Silicone -based lubricants do not contain any water. They offer a different feel from water-based personal lubricants.
Silicone-based lubricants are not absorbed by skin or mucous membranes and consequently last longer than water-based lubricants. Many different silicone lubricants are commercially available, with varying quality and performance. Not all silicone-based lubricants are certified latex-safe, but silicone-based lubricants have not been shown to increase the risk of HIV transmission during anal intercourseas some water-based lubes have.
Silicone-based lubricants are not usually recommended for use with sex toys or other products that are made from silicone because the formula may dissolve the surface, making it sticky to the touch, and cause disintegration of the item over time. In most cases, a warning is listed on the product label. Silicone-based lubricant is also used in the manufacture of pre-lubricated condoms, due to its long-lasting properties and superior latex compatibility. Vaginal lubricants are used to reduce vaginal dryness and pain during intercourse, and by couples trying to conceive.
During fertility interventions, the use of a lubricant eases sperm specimen collection by sex. Commonly used lubricants include salivaoil such as baby oilolive oilcanola oilor mineral oil or commercially available lubricants that are either water-based or hydroxyethylcellulose-based. Human saliva and olive oil have been found to be detrimental to sperm function. Vaginal lubricants such as mineral oilcanola oilor hydroxyethylcellulose-based lubricants are recommended anal use by anal attempting conception by The Practice Committee of the American Society for Reproductive Medicine.
Many lubricants are safe for anal sex, but there are products that are specifically marketed or designed to enhance enjoyment of anal sex. Often, this is simply a thicker gel rather than a liquid. This thicker consistency is preferable because it helps the lubricant stay in place. Some anal lubricants contain numbing agents to relieve discomfort during anal sex, although it is generally inadvisable as a lack of sensation makes accidental injury more anal.
Additionally, a commonly used numbing agent benzocaine can cause an allergic reaction in those with an allergy to PABA 4-Aminobenzoic acid. Some lubricants are conveniently packaged for ease of application. Because of strict FDA guidelines for medical devices, organic personal anal were no longer allowed to carry a USDA seal for Nude Personal Lubricant, and that it should be very careful about using the term organic anywhere on its label.
Many of these types of lubricants also market themselves as "natural" and do not contain paraben, glycerin, DEA or animal-based ingredients. Some contain botanicals such as aloe anal or plant extracts. Warming lubricants contain specific ingredients to cause a sensation of sex. Breathing on these types of lubricants may increase the effect. Some lubricants are sold together, such as "hot and cold", or are marketed for a specific use or effect.

Lubricants with osmolalities closer to that of the body, such as agar-based lubes, did not damage the tissue samples or boost HIV infection rates.
Some may experience irritation from the use of certain lubricants. Some lubricants as mentioned above latex 'Water-based' have been found to damage cells or even increase the replication of the HIV virus.
