Nearly one in ten sexually active teenagers lead a bisexual lifestyle, a new study has found. The trend of changing partners among teenagers is also increasing. Specialists appeal to the mandatory use of protective equipment in such cases. A study published in the journal Pediatrics of 17,000 New York teenagers found that those who had a same-sex or mixed-sex partner were at a much higher risk of sexually transmitted infections. diseases. Half of the 18 million new cases of sexually transmitted diseases among people are in people between the ages of 15 and 24, say experts from the Centers for Disease Control and Prevention. This is due to the risky behavior of teenagers who do not use condoms during sex or have forced sex. More than half of boys who engage in bisexual intercourse do not use protection, compared to a fifth of boys who lead a heterosexual lifestyle. The difference is not as great for girls, but it is similar. Elizabeth Saivik of Columbia University told Reuters that the lack of enough conversations with teenagers about homosexual and bisexual relationships is one of the main problems that lead to the spread of sexually transmitted diseases. Parents and educators should pay more attention not only to sexual identity, but also to the sexual behavior of teenagers, experts advise. Teaching safe sexual behavior is a key factor with teenagers, due to the fact that at this age their desires are constantly changing.
