Which poses the greatest risk of getting an STIs?

Engaging in unprotected sexual intercourse, particularly with multiple partners, poses the greatest risk of contracting sexually transmitted infections (STIs). This includes not using condoms or other barrier methods, which significantly reduce the transmission of STIs. Additionally, activities such as sharing needles or engaging in sexual practices that involve open sores or blood can further increase risk. Regular STI testing and open communication with partners about sexual health are crucial for reducing the risk.
