Ejaculating into a partner’s mouth is a common practice during oral sex/fellatio. In a safe situation (where there is no danger of catching an STD), the semen-receiving partner may choose to spit the semen out, or to swallow it.

If not, please use barriers for oral sex and abstaining from making contact with ejaculate. Semen is mostly water, but also contains amino acids and protein, sugars such as fructose and glucose, minerals such as zinc and calcium, vitamin C, and a few other nutrients. Sperm cells themselves make up less than one percent of semen. Semen is edible, and if swallowed, will travel down the esophagus and into the stomach, where it will be digested in the same way that food is. You can never get pregnant by swallowing semen. Some people accept the taste of semen, but others complain that swallowing semen can give them an upset stomach. In rare cases, you may have an allergy to the proteins found in semen. What does It Taste Like? The taste of semen varies. Bitter, sweet, metallic. So, one may expect to find the taste of semen anywhere from enjoyable to tasteless to disgusting. But there is a way of controlling the taste of semen, which is through diet. Keep track of the diet, and communicate with the partner about when it tastes better or worse.
