Fellatio

Fellatio is a form of oral sex in which the penis is stimulated by the partner's mouth, lips, and tongue. It is typically performed as part of consensual sexual activity between adults and may occur in various sexual partnerships.

The term fellatio comes from Latin fellāre, meaning to suck, and is used in medical and educational contexts to describe the act in neutral terms.

Practices vary widely and are shaped by personal preference, anatomy, and communication. Some people incorporate hand stimulation or alternate between different techniques and speeds. Consent and comfort, including boundaries and safe words, are essential.

Safety concerns include the transmission of sexually transmitted infections (STIs). Oral sex can transmit infections such as gonorrhea, chlamydia, herpes, human papillomavirus, and HIV, though risk varies and is generally lower than for vaginal or anal intercourse. Protective measures include condoms on the penis, dental dams or other barriers on the receiving area, good oral hygiene, and avoiding activity when either partner has active symptoms.

Pregnancy is not possible from fellatio alone, but semen contacting vaginal or anal openings can lead to pregnancy in the latter case; generally pregnancy risk is considered negligible. In health education, fellatio is described as a potential route for STI transmission, so safe practices are encouraged.

Attitudes toward fellatio vary across cultures and legal systems, but it is generally discussed within the context of adult, consensual sexual activity. Age of consent laws and decency standards apply.
