Unprotected sex refers to sexual intercourse that occurs without the use of barrier methods, such as condoms. This practice can increase the risk of sexually transmitted infections (STIs) and unintended pregnancies. Barrier methods are designed to provide a protective layer that reduces the exchange of bodily fluids. Engaging in unprotected sex can have significant health implications. Individuals may be exposed to infections like HIV, chlamydia, or gonorrhea, which can lead to serious health issues if left untreated. Additionally, unprotected sex can result in unintended pregnancies, which may require individuals to consider options such as parenting, adoption, or abortion.
