STIs, or sexually-transmitted infections, are very easily spread and transmitted from one person to another through unprotected sex. So, those that engage in anal, oral, or vaginal sex without using condoms are very prone to contracting these diseases.

Common STI symptoms
Once STIs infect a person, they may trigger some signs and symptoms. Here are the most common ones:
  • - lower abdominal pains
  • - rashes
  • - sores
  • - lesions
  • - pain when urinating
  • - itchiness in the genital region
  • - odd discharge from the genitals
  • - testicular pain (men)
  • - bleeding after sexual intercourse (women)
  • - bleeding in between menstrual periods (women)
  • - headaches
  • - flu-like symptoms
If you notice these symptoms occurring on you or your partner, you have to undergo an STI test or STD test immediately. Diagnosis of these illnesses early on is very important to avoid serious complications.
