Q: Upto what percentage condom can prevent infection of AIDS and other STDs?Which condom is suitable for oral(penis in mouth) sex.

A:A condom in good condition, properly applied with adequate lubrication, used from before the first contact between penis and any opening such as vagina, mouth or anus, used till the end of contact can prevent MOST sexually transmitted infections. Please note however that the condom can break or tear and thus expose the person to the risk of infection. The condom is NOT 100% safe because accidents can happen.
