Oral Sex Is Harmful for Health- Myths & Facts, FAQs, More | Bodywise

As per the Centers for Disease Control and Prevention, involving the mouth to stimulate the genital parts (clitoris, penis, anus) is called oral sex.

Oral sex is common among sexually active people, especially those between 18 to 44 years of age. However, as per a study, almost 55 per cent of males and females aged between 15 to 19 years have had oral sex at least once with the opposite sex.

Oral sex is of three types - fellatio (stimulation of the penis with the mouth); cunnilingus (clitoral and vaginal stimulation with tongue); anilingus (stimulating the anal area with tongue).

This article will discuss the benefits and side effects of oral sex and demystify the myths and reveal the facts about oral sex.

Is Oral Sex Is Harmful for Health?

Is oral sex harmful for health? No, oral sex is not harmful if both partners are tested negative for sexually transmitted diseases. However, if you and your partner are not aware of your STDs status or about any unknown condition that might lead to infection, then you must abstain from oral sex.

Oral sex is a safer option when compared with penetration sex. In a healthy relationship and a satisfying sex life, oral sex plays a major role. However, there are a few facts that most people are unaware of about oral sex. These facts are:

1. Throat Cancer From Oral Sex

As per research, oral sex is associated with oropharyngeal cancer (oral and throat cancer). The study concluded that having multiple oral sex partners may increase the risk of developing throat cancer. However, the study discussed that the oral sex that leads to throat cancer is mostly unprotected.

Unprotected sex may transmit infection-causing microorganisms to your oral cavity and the body, making you vulnerable to sexually transmitted infections. Hence, you must make sure that your partner wears a condom before fellatio. It is important to note that you and your partner must use genital wash before getting involved in oral sex.

2. Stress From Oral Sex Due to Oral Hygiene Concerns

Concern about your oral hygiene may give you stress while planning for oral sex. The idea of having oral sex can make you anxious, especially if you are going to indulge in it for the first time. The best way to overcome anxiety and stress is to make sure that your partner uses genital wash and is wearing a condom.

3. Health Risks From Oral Sex

As per a study, oral sex may lead to oral cavity infections, genital areas, and even respiratory tracts. Considering it to be safe in terms of no chances of pregnancy, unprotected oral sex is very common, exposing you to several sexually transmitted infections such as

  • HPV

Is Oral Sex Safe Without Protection?

As per research, unprotected oral sex is not completely safe and may lead to sexually transmitted diseases like HIV, Herpes, Syphilis, and HPV. As per another study, oral sex is considered a risk factor for sexually transmitted infections. Unprotected oral sex may transmit the infection-causing microorganisms if:

1. Your partner has genital or a rectal STD, and you indulge in fellatio or anilingus with them.

2. Your partner has any oral infection, and you indulge in cunnilingus or anilingus with him.

Indulging in anilingus increases the risk of developing sexually transmitted diseases. It is important to note that not all STDs show symptoms, and hence you may get infected without realising that you have contracted the infection. Hence, unprotected oral sex must be avoided. If not possible to avoid, make sure you and your partner disinfect the genitals with a mild genital wash before having oral sex.

As per a study, adolescents who had oral sex showed a higher prevalence of a parasitic infection called toxoplasmosis. The prevalence was higher among females involved in fellatio (stimulation of partner's penis with mouth) and ingested the semen. The study reported that swallowing the semen (ejaculation from the penis) may result in the transmission of toxoplasmosis cysts in the body leading to a fatal infection.
