11.5. Prevention and sexual hygiene

Prevention and hygiene of sexually transmitted diseases

We will start this section with a simple game. You just have to number three small papers with a number 1, 2, and 3 and put your name next to that number. Then follow the instructions in the video. Do not worry about more, then you will know what we are doing all this for.

The best remedy to eliminate STDs is their prevention, avoiding contagions avoids their transmission. That is why it is in adolescence, when you must acquire healthy habits to prevent the spread of sexually transmitted diseases and acquire sexual hygiene habits.

  • It is necessary to perform good daily hygiene of the external genitalia.
  • The man must remove the foreskin and clean the folds of the glans, to eliminate bacteria that can cause infections.
  • The woman has to remove the labia majora and minora and clean well, from front to back to prevent microorganisms from the anus from infecting the vagina. Over-washing the vaginal area can destroy the vaginal flora and there is a greater risk of other microorganisms causing an infection.
  • The use of condoms during sexual intercourse is essential both to avoid unwanted pregnancies and to avoid the spread and transmission of STDs. You should eliminate any risky practices, such as having sex without a condom or with strangers who are not known to have any type of STD.
  • The woman has to change pads or tampons frequently during menstruation, but not flush them down the toilet. The day the period starts and how long it lasts should be noted.
  • If menstruation is accompanied by abdominal pain, it may be advisable for the doctor to prescribe a pain reliever.
  • The girls have to visit the gynecologist from the moment they have the first menstruation, and if something strange is found in some self-examination of the sexual organs, you should also visit the doctor. It is advisable to periodically examine the sexual organs.
  • The existence of any sexually transmitted disease must be known to the couple to avoid its transmission.
