Fellatio, commonly known as a blow job, is oral sex performed upon the penis. It may be done as foreplay prior to having sex or to induce orgasm and ejaculation. You can get Sexually Transmitted Infections (STIs) including HIV by giving fellatio. Use a condom on the penis during fellatio to avoid the transmission of body fluids. Protect yourself against HIV transmission and STIs every time you have oral sex.
