Condoms are hard to break but mineral oil, like Baby Oil degrades the rubber and "POP" it's broken. Use only water based products like KY or Astrolube. Vegtable Oils like Almond Oil will not hurt rubber condoms but may promote a yeast infection in your partner. Also condoms don't age well so if you have been carrying a condom around in your wallet for the last few years it's more than likely no good. Buy a new one and allways bring your own. Avoid pre-lubricated condoms with spermicide such as Noxy-9. Many women have a allergic reaction to it.
