A BJ, or blowjob, is a sexual act involving oral stimulation of a male's genitalia. This practice can be part of sexual activity between consenting adults and is often considered a form of foreplay or a standalone sexual encounter. The act can vary in technique and intensity, and preferences may differ among individuals. Safety practices, such as using protection like condoms, are recommended to reduce the risk of sexually transmitted infections (STIs) during oral sex. Communication between partners is essential to ensure comfort and consent.
