Most STDs are transmitted via skin-to-skin contact, oral-to-genital contact and oral-to-anal contact. Nevertheless, swallowing your boyfriend's sperm will not always make you get an STD, unless he's infected with an STD which attacks the mucous membranes in the mouth or throat.
Besides, it also doesn't really matter whether he ejaculates in your mouth. The little friction that can occur during oral sex could still put you at risk of getting an infection.
While most people believe that STDs like chlamydia and gonorrhea are only transmitted when the man ejaculates in your mouth, this is not the case, you can still get an infection even if the guy doesn’t ejaculate in your mouth. The causative agents responsible for these infections live in the epithelium of the mucous membranes, i.e. the cells lining the infected person’s urethra as illustrated here and here.
The bacteria living in these cells can move to your throat, irrespective of whether the guy ejaculates in your mouth or not (pre-ejaculates). When you get the infection through oral sex you can develop wounds and sores around the mouth and lips as the disease manifests itself in your system.
What are the Risks of HIV Infection if I Swallow My Boyfriend's Sperm?
There are no definitive studies which have discussed whether you are at higher risk contracting HIV when you swallow semen compared to spiting it out.
What we do know, concerning HIV transmission, is that the risk of getting the virus from oral sex is very low irrespective of whether you swallow or spit out the semen. If you're worried however about your chances of getting an infection from swallowing your BF's sperm, it's advisable that you talk this up with him.
Which STDs Can I Get By Swallowing Semen?
Theoretically, if you have engaged in oral sex which ended up in your partner ejaculating in your mouth, you could contract various STDs due to genital to oral contact.
This is more common if you have open sores or gingivitis in your mouth, allowing the virus or bacteria to more easily wreak havoc in the body.
Here are some of the STDs which can be transmitted by swallowing semen from an infected person.
Hepatitis B is a virus that lives in the bodily fluids and blood of an infected person. Hepatitis B usually infects the liver leading to diseases like liver cirrhosis and cancer.
The symptoms of hepatitis B may not be noticeable in most patients. When symptoms do appear, the patient can experience abdominal pains, jaundice, fever, nausea and dark urine among others.
This infection can be transmitted when you have contact with the infected person's blood on an open wound or from sex. It can also be transferred from one person to another when the recipient swallows the semen of an infected person.
Expectant mothers can also transmit hepatitis B to the baby during delivery. You can protect yourself from hepatitis B by getting vaccinated.
Gonorrhea is a sexually transmitted bacterial infection. While it's easy to treat (in the early stages) with antibiotics, many people don't notice that they have gonorrhea.
It's carried in various bodily fluids, including semen of the affected persons and can infect the eyes, throat, penis, urethra, cervix and the vagina.
Having unprotected oral sex will put you at a higher risk of contracting gonorrhea, if your partner is a carrier. It can spread when semen gets into contact with your mouth or you swallow it.
You can also get it if you touch the semen with your hands, and then use the hands to rub your eyes. A mother can also pass it over to the baby during childbirth.
Symptoms of gonorrhea can be troublesome to spot, but any of these occurrences should raise red flags. These symptoms may appear after around seven days. In females:
- Pain and burning sensation when urinating.
- Abnormal vaginal discharge which could be bloody or yellowish.
- Bleeding between your periods.
Males may experience these symptoms:
- Pain or swelling of the testicles.
- Pain or burning sensation when urinating.
- Abnormal discharge from the penis which can be white, green or even yellow.
Herpes is a common viral infection. There are various herpes types. The most common strains are Herpes Simplex 1 (HSV-1) and Herpes Simplex 2 (HSV-2). Both strains can cause oral and genital herpes.
During transmission, these virus strains attack the mucous membranes on the skin. The resulting symptoms after a herpes attack may include fever blisters on the mouth and around the lips.
The HSV-1 strain is the primary cause of oral herpes, though studies have also linked the HSV-2 to cause the infection. Both strains can be transmitted via oral sex.
This is because HSV-1 and HSV-2 live in the body fluids, in pre-ejaculate, sperm and vaginal fluids. These viruses act on the cells of the body by replicating themselves in the cells and destroying them.
This is what results in the development of blisters that are filled with fluids and sores on the body. Scabs will form on the blister sores and disappear without any scarring when the liquids are absorbed.
Human Papillomavirus (HPV)
Like most other STIs the Human Papillomavirus also lives in the semen. It's an infection which leads to the development of warts on different body parts, though this will depend on the strain of HPV.
HPV is an extremely prevalent viral infection, with in the USA over 14 million people getting diagnosed with new HPV infections each year. When you swallow semen with the HPV virus, you can develop cancers of the throat and mouth.
It can also cause genital and oral warts. Reports suggest that over 19,000 women and over 12, 000 men in the US are diagnosed with cancers due to HPV each year.
How to Prevent STD during Oral Sex. Does Swallowing or Spitting Semen even Matter?
Spitting or swallowing your BF's sperm is a matter of choice. If he's a carrier of a common STD like HIV/AIDs, gonorrhea, syphilis or HPV, it's very much possible that you'll get an infection, especially if you have sores in your mouth.
Some slight friction may also cause a tear in the mouth, opening more routes for the virus or bacteria to attack your defense system. For maximum protection during oral sex, be sure to use a condom. You can use scented condoms to get rid of the latex taste to make oral sex more pleasurable.
The golden rule in the defense against STDs is knowing whether you have an infection and taking the necessary precautions. You can also get vaccinated for infections like hepatitis b and HPV.
Be sure to also go for regular medical checkups if you give oral sex to more than one partner or if you suspect that you were exposed to any infection. To screen yourself at the privacy and convenience of your own home, you can also get these certified rapid STD test kits.
