Condoms and lubricants sometimes contain a spermicide called Nonoxynol 9. Adding Nonoxynol 9 to condoms was thought in the past to help to prevent pregnancy and the transmission of HIV and other STDs, but it is now known to be ineffective.
Some people have an allergic reaction to Nonoxynol 9 that can result in little sores, which can actually make the transmission of HIV more likely. Because of this, you should only use condoms and lubricants containing Nonoxynol 9 if you are HIV negative and know that your partner is too. However, using a condom (even if it contains Nonoxynol 9) is much safer than having unprotected sex.
