Semen is a substance that exists to contain sperm while the sperm travel to impregnate an egg. In order to make this long and difficult journey it must contain various nutrients to support the health of the sperm.
Many people consume semen during oral sex for their own or their partner's pleasure. Some people also like to consume their own semen. So is it safe? Let's cover the different aspects of semen, and how they relate to the safety behind eating cum.
The short answer is, yes, it's safe to eat semen. Semen is made up of vitamins and minerals that many people take as a dietary supplement, or already naturally occur in your body. Among those nutrients:
As you can see there's nothing unsafe in the makeup of semen (1). Many of those nutrients are sought after! Unfortunately the amounts of these nutrients within semen are small enough that they're unlikely to have a nutritional impact on your diet.
The average ejaculation is 1ml to 5ml of semen. That's a relatively small amount of liquid compared to other foods or drinks you might consume. Being that an ejaculation is such a miniscule amount of liquid volume, it's extremely unlikely that one could consume enough cum to have any dietary effect.
If you're eating your own cum rather than a partner's, it's doesn't change the safety of the situation for the negative. In fact, it's safer to consume your own semen, as there isn't the possibility of catching an STD from a partner.
The short answer is no, you can't get pregnant from oral sex. For pregnancy to occur, the sperm must travel through the vagina to fertilize an egg. Since semen consumed orally would go into the stomach after being swallowed, it would never have a chance to reach the vagina, or the egg.
There is, of course, an exception to most things. One bizarre case involves a girl that has a birth defect causing her to have no external reproductive organs. She didn't eat that day, performed oral sex, and swallowed the cum. Later she was stabbed, which caused the semen to leak into her reproductive organs. Due to not eating her stomach was at a safe enough Ph level for the sperm to survive. This is an absurdly rare case, where everything had to happen exactly as it did! (2)
The main ingredient in semen is water, so the most simple step you can take in trying to improve the taste of your semen is to drink more water. Next, water is made up of various forms of sugars including Fructose and Glucose. Natural sugars found in fruits are a great way to supplement these sweeteners.
The next option is Bromelain. Bromelain is a protein-digesting enzyme mixture derived from the stem, fruit, and juice of the pineapple plant. Bromelain is also taken as a supplement to improve the taste of male ejaculate ("precum" and "cum"). Regular supplementation imparts a sweet or lightly fruity flavor. This effect is well-documented anecdotally.
There is no simple answer, as it depends on the person. Some common descriptions of the taste of semen include, salty, sweet, and thick. Some people note that semen has the smell of bleach, but doesn't taste like what it smells like.
Acidic foods like coffee can give cum a more acidic taste. Some people say that eating more fatty meat like beef can give it a salty taste. As we stated above, eating foods with natural sugars like fruits can give semen a sweeter taste.
Smoking cigarettes is known to give semen a bad, bitter taste.
The ingredients that make up semen are generally considered safe. Some people have reported to have had allergic reactions to cum, but this is extremely rare. The biggest risk when swallowing semen is getting a sexually transmitted infection (STI, STD). It's possible to contract herpes, syphilis, and gonorrhea from performing oral sex and eating the semen.
Studies have shown it’s more difficult to get the human immunodeficiency virus (HIV) from oral sex but not impossible. Semen is known to carry the human papillomavirus (HPV). But HPV is undetectable in semen when tested. Some strains of this virus can cause throat cancer.
If there's any question of the health of a partner, it's best to not consume their semen.
