Along with English, math, and science, most high school students were subjected to learning about sex education.
While it can be an uncomfortable subject for some, eventually getting into a relationship is inevitable and it's important to protect your health.
But if you thought you were finished learning about the birds and the bees, you'll have to get caught up on the resurgence of a gruesome, flesh-eating sexually transmitted disease (STD).
In the last 12 months, an unnamed woman in Southport, England had been diagnosed with donovanosis, which causes flesh-eating ulcers on an individual's genital tissue.
According to the Liverpool Echo , the woman, who is between the age of 15 and 25, is the first person to have been diagnosed with the rare disease in the UK, which is generally found in countries such as India, New Guinea, parts of the Caribbean, central Australia and southern Africa.
The Centers for Disease Control and Prevention (CDC) said that while donovanosis is painless, it will cause progressive ulcerative lesions on the genitals or perineum.
It can lead to "infections to the pelvis, or it can disseminate to intra-abdominal organs, bones, or the mouth."
The lesions can be at risk for secondary infections, and those with the disease are also prone to experience heavy bleeding.
Even though the condition can be cured, patients must be treated with antibiotics, there is potential for a relapse between six to 18 months later.
If left untreated, individuals are susceptible to permanent genital damage and scarring, loss of skin colour and irreversible genital swelling.
Pharmacist Shamir Patel, of Chemist 4 U told the Liverpool Echo that since the disease is "so uncommon in the UK," it's possible the early-stages of donovanosis can go undiagnosed.
"Although antibiotics can treat donovanosis, early-stage cases might be going undiagnosed because it's so uncommon in the UK," Patel said.
"Bacteria that cause the disease, known as klebsiella granulomatis, infect the skin around the genitals, groin or anal area and causes lesions and skin disintegration as the flesh effectively consumes itself."
"This bacteria is also a risk factor in the transmission of HIV."
In the United States, 110 million people are living with some type of STD, with 20 million new infections being reported each year, according to data from the CDC.
