Natural physiological lubrication from a woman (e.g. human vaginal secretions as a woman gets sexually stimulated) is perfect for vaginal penetration.

This is where sex toys can help in the absence of a woman. Sex toy use is associated with a range of benefits including increased sexual functioning, sexual pleasure and your overall sex life.

Sometimes, we need to get things going ourselves because your pocket pussy and sex doll can’t naturally lubricate themselves.

It is because of this reason that there are several man-made lubricants available on the market.

Among these artificial lubricants, there are several different types of lubricants each with its pros and cons and situational uses.

There are silicone based lubricants, water based lubricants, oil based lubricants, hybrid lubricants, and novelty lubricants (warming, cooling, tingling, etc). Some of these lubricants are designed exclusively for use on human skin and can NOT be used on your sexy sex doll, pocket pussy or any male masturbator for that matter.

If your toy is made from a hard material, like natural stone, ABS plastic, glass, or stainless steel, then the world of personal lubricants is your oyster.

Though I'm not sure about you but I wouldn't want a sex doll made of natural stone, ABS plastic, glass or stainless steel...

Many people like to use their best lubes with their favorite sex toys but not all lubes are suitable for sex toy use, and some of them definitely work better than others.

So, which type of lubricant should you choose for your love doll?

Is there a risk of damaging your realistic love doll’s skin?

Let’s find out!

Of course, you can use the secretions from your own body (for example, saliva) to lubricate your silicone & TPE sex doll.

However, I do not suggest using your own secretions as your natural secretions do not last very long and could lead to increased bacteria and mold growth, depending on the cleanliness of your secretions and how well you clean your sex doll after use.

Other possible drawbacks include limited quantity and emits an unpleasant odour.

Yes!

Water-based lubes are compatible with the largest variety of sex toy materials making water-based lubricants your best option by a long margin.

Water base formulas are usually the least irritating as they are often made from naturally moisturizing ingredients like Aloe Vera or Carrageenan.

Water based lubricants boast many benefits that are, but are not limited to, high efficiency and ease of cleaning.

Water based lubricants are environmentally friendly, anti-allergenic, non-sticky and non-greasy making them ideal for use on adult sex dolls made of silicone and TPE.

Water-based lubricants will also protect you and your sex doll from stains.

The downside of water based lubricants is that they are not suitable for use in combination with water, such as in the shower or bathtub.

NO!

Silicone is a hypoallergenic material, so as long as it isn't combined with any irritating ingredients, it's safe and recommended for sensitive skin. 

Silicone based lube is the silk sheets of sexual lubricant. 

Silicone based lubes are extra smooth and not absorbed into the skin, so it lasts longer during play. Silicone lube also doesn't wash away with water alone, making it ideal for shower and bath sex.

Silicone lubes are also compatible and ideally used with natural rubber latex, polyurethane, and polyisoprene condoms.

However, silicone lubes do have their limitations. TPE and Silicone toys can be ruined just through the use of silicone based lube (though condoms are fine), and silicone lube can create unsightly stains on your bedsheets and clothing.

It is important to emphasize that it is absolutely forbidden to use silicone lubricant on silicone and TPE sex dolls.

Silicone lubricants are excellent for lubrication and are easy to clean, but can not be used in conjunction with TPE or silicone sex toys ever, as this will cause irreversible damage to your sex doll.

Silicone lubricant will react with any silicone or TPE material to produce a gloopy mixture that will cause irreversible and long term damage to the skin or holes of your love doll and may even make use of your sex doll impossible.

While it's great for anal play and vaginal sex because of the cellulose thickening agent (meaning that yeast infections are much less likely), the thicker texture does taste and feel strange orally, so it's advised to avoid this type of lube if you're looking for a lube to use during oral sex.

Oil based lubricants are the lubes that just keeps on going.

Loved for their longevity, oil based lubes can also double as a sensual massage oil. 

Oil-based lubes are great for anal sex since you need a lot of lube for backdoor play. In fact, using any personal lubricant makes anal sex much safer.

However, oil based lube can impact the use of latex condoms, a common tool used to prevent the transmission of STIs and unwanted pregnancies. The oil breaks down and creates weak spots in latex condoms making them more prone to breakages. Oil based lubes are also associated with higher rates of infections as they can quickly go rancid.

Furthermore, you will want to keep your sex toys far away from oil based lubricants.

Oil based lubricants are never recommended to be used with your sex doll.

Not only will using an oil based lube makes the surface of your life size sex doll‘s skin overly slippery, but oil based lubes are also extremely difficult to clean.

Please, do not use an oil based lubricant with your sex doll. Believe me, your doll will get stained and you’ll never be able to fully clean all of the lube up!

It's important to note, I do not recommend oil based lubricants at all. 

Don't even try them. 

Not only should oil-based lubes not be used internally, as they can coat the anus or vagina preventing the body from adequately cleaning itself but they also shouldn't be used on your sex toys.

Regardless of the sex toy material, oil-based products (including lubes, creams, and massage oils) will coat your toy in a film of oil, where the only way to remove the oil off of your toys is by using chemicals that aren't going to be very friendly to your toy or your body. 

Basically, stay away from oil, period.
