Health care professionals suggest that safer sex practices such as the use of condoms should always be used in sexual activities, but they should by no means be considered an absolute safeguard. The best suggestion is to avoid sexual activities with anyone known to have a sexually transmissable disease, and indeed anyone whose disease-negative status you aren't certain of.
