Latex and polyurethane are the way to go
Latex or polyurethane condoms are the only ones that protect against HIV infection.
Fresh condoms are good condoms
Check the expiration date on the condom wrapper; if it has passed, throw it away! Also look at the condom itself - does it seem dry, brittle, stiff or unusually sticky (gross!)? Don't take chances, use a different one.
How to store your condoms
Store your condoms in a cool, dry place so they don't get damaged. Heat and excessive wear can cause a condom to tear during sex - glove boxes, back pockets, wallets and window shelves are all bad places to keep your condoms.
Use lubrication
To make sure a condom doesn't tear or come off, use some water-based lubricant inside and outside the condom. Be sure not to use an oil-based lubricant like Vaseline or other petroleum jellies, body lotions, mineral or vegetable oils - they can cause the latex to break down. Also, studies have shown that lubricants with nonoxynol-9 (a product often used in spermicides) may actually increase the risk of HIV transmission during sex and are not recommended as an effective means of HIV prevention.
Wear it well
Make sure the condom is on correctly before getting started. Use it every time.
