This is actually a lie spread by abstinence only sex ed campaigns, not anything that has any bearing on reality. Condoms are made of latex, the same thing surgeons' gloves are made out of, specifically because they're so great at blocking the transfer of fluids and pathogens.
Good to know!
Protip: Its actually quite easy to track down lambskin condoms (... notes the person with a latex allergy). Polyurethane variants appear to be on par with latex analogs, but be careful with lambskin variants as they are not as effective in this regard.
Note, that does not diminish the risk of indirect vector transmission. And while many of these pathogens die quickly, some can last quite awhile - hours in some cases (like herpes), longer in others (such as hepatitis).
Which is an important note, because robot-sex is laaaaame... Unless it involves actual robots, in which case its pretty awesome.
Also, cars have a far greater tendency towards crashes due to operator error - especially when that operator has been drinking. Something to consider when taking that lovely someone home after a night out.

Anyway, I'm just saying I'm inclined to believe the whole viruses able to move through pores in latex thing, though I can't find a source either way right now. If you had one that would be very helpful.
"Laboratory studies have demonstrated that latex condoms provide an essentially impermeable barrier to particles the size of STD pathogens."

(Already something similar linked, but here's a direct line to valuable information nonetheless)
That said, as with all biological systems, sexually transmitted diseases are a constantly evolving model. Thus, while it appears latex (and polyur) condoms are a safe bet for the time being, it cannot necessarily be assumed this will remain static into the future... But for now, it appears you'll have a layer of protection against direct contact.
Note however, to quote the abstract of a study regarding pathogen permeability of latex gloves:
"The literature data indicate that glove composition, glove manufacturer, glove design (examination vs. surgical), and mechanical manipulation had considerable influence on glove performance when tested for leakage and viral penetration."
One would assume similar variations of circumstance can effect the function of condom efficacy; granted, condoms are made to a higher standard than gloves and receive a second coat of latex (gloves only one). That said, dish out the few extra bucks - or pennies - for a new, quality condom and learn how to use it properly. You won't regret it.
And from the above CDC link: "Ensure that adequate lubrication is used during vaginal and anal sex, which might require water-based lubricants. Oil-based lubricants (e.g., petroleum jelly, shortening, mineral oil, massage oils, body lotions, and cooking oil) should not be used because they can weaken latex, causing breakage."

So, if you're going to lube-up, pay attention to what you use!
