Hand sanitizers are effective in killing bacteria as long as they contain 62% or more alcohol or isopropyl alcohol. See www.cdc.gov/ncidod/EID/vol12no03/05-0955.htm

I'm not sure about viruses.

If you are really adventurous you could use 110 proof or greater Tequila or other liquor of your choice. Remember "proof" relates to percent by 7:4. So 70 proof is only 40% alcohol. The good thing about this is you can have your next partner lick the excess off you. But it is an expensive choice.

You can always just use the rubbing alcohol, as long as it is at least 62% isopropyl alcohol (or isopropanol), but don't lick or drink that. BTW both high proof liquor and high percent isopropanol are flammable. I have also considered using hydrogen peroxide as a cleansing agent.

I would recommend that you and your partners consider using gloves if you are poking your fingers or hand in vaginas or anus, and change them when changing partners. I suspect that a friend's case of bladder infection after a recent party was due to fingers in more than one person. I like Black Dragon brand gloves. They are black color and often used by tattoo artist. Check about latex sensitivity with partners.

BTW, if you want to PLAY at Burning Man, like who doesn't want to, you also got to deal with the playa dust. Playa dust is alkaline nasty stuff. I used baby wipes to do quick clean ups and I have access to a shower. I camp with Greeters and greet for several shifts during the week. Those that are Burner Virgin (first timers) are lucky enough to be greeted by me, and they do as I tell them will leave the greeter station with their entire naked body cover in playa dust. I know that is EVIL. Hey, someone has to do it!

See you at the Playa,

El Guajiro

here are feminen wipes avalibel. the good part about them is they do not disturb PH and for many women thats important.

I've wanted to produce a safer-sex product for a while that is essentially a disposable latex harness that can be sealed to a condom via a cock ring. This way, you'd have a triangular piece of latex covering a bigger area and more fluids. Not to mention that this would better protect against herpes and warts. I figure this product would be competitive at $5 a pop.

Anther variation would be to manufacture the product with the condom already part of the deal, for a totally foolproof safer sex product. This would probably cost more to manufacture, but there would still probably be a market for it amongst those who are STD positive and those who are very sexually active, to provide that much more risk management.
