A blowjob, also known as fellatio, is a sexual act involving the stimulation of a man's genitals using the mouth. This intimate act can be a pleasurable experience for both partners and is often part of foreplay or sexual activity. It can vary in technique and intensity, depending on personal preferences. Blowjobs can also involve the use of hands and other forms of stimulation to enhance pleasure. Communication between partners is essential to ensure comfort and enjoyment. Safety practices, such as the use of condoms, can help reduce the risk of sexually transmitted infections during oral sex.
