Spit or Swallow? What Do You Prefer?

Animals and humans enjoy fellatio as their popular pastime, but the after-effects of this excitement can cause a little bit of a problem. The question then arises for the people who are administering it, as to whether one should spit it or swallow it. It is a great idea to just read up something about semen before you make a decision about swallowing or spitting.

Looking At The Arguments: Spit Vs Swallow

Let us look at the positives of swallowing, first. A 2002 study found out that the hormones in semen can positively affect a person’s mental health. The participants in this study were inseminated through the vagina and not through the oral pathway and were observed. The study was completely observational, so, no causal link between emotional wellness and semen was established. The results were still interesting. 

According to the authors of the study, they found out that the women who had sex without protection were discovered to have lower scores in depression than the ones who used condoms. They also found out that “depressive symptoms and suicide attempts among females who used condoms were proportional to the consistency of condom use.” 

The confirmation of such an effect needs more thorough research but the researchers pointed out that the semen contained several mood-boosting compounds like serotonin and oxytocin. These were also detected in the blood of recently inseminated women.

It cannot be proved if the same effects would be observed after swallowing the semen but it has been found out that male ejaculate contains around 5,000 milligrams of protein per 100 milliliters. It also contains a high dosage of zinc and tiny portions of potassium, magnesium, and Vitamin C. It is advised that you get these nutrients from actual food instead of sucking on willies to sustain yourself on semen. Nevertheless, an extra source of nutrients never hurt anyone.


Apart from the nutrients, semen also contains spermidine, which is an antioxidant. This substance plays a role in slowing down aging in worms, yeast, mouse liver cells, and house flies. Such a thing is attributed to autophagy, which is the ability to regulate a cellular recycling process. It is still unlikely that such a benefit can be attained from swallowing semen.

Looking At The Arguments For Spitting The Semen Out

Now let us look at the arguments presented by Team “Spit”. It has been found out that swallowing semen increases the risk of you catching a terrible STD such as herpes, hepatitis, or even HIV. Such diseases can even be transmitted without the act of swallowing but infections are more likely to occur if the administrator of oral sex has an open sore or a cut, in or around their oral cavity.

It might also be a necessity for some to spit, as they suffer from an allergy to ejaculate, also known as the human seminal plasma (HSP) hypersensitivity. Such an allergy is caused by certain proteins from the prostate and the HSP hypersensitivity can produce systemic or local symptoms and in turn, make it impossible for some to have unprotected intercourse.


It is fortunate that such a condition is very rare and should not be a concern for the large majority of people who participate in oral sex. 

So, in conclusion, spit and swallow carry both positives and negatives and one can make a decision based on nothing but their personal preference.
