You can get an STD from just one unprotected sexual encounter, as the risk depends on your partner's infection status, not just the number of partners, though more partners increase overall risk. The chance of transmission can be high even with one partner (e.g., ~30% for syphilis, gonorrhea, chlamydia in one unprotected encounter) and rises significantly with multiple partners and no barrier protection like condoms. Limiting partners, consistent condom use, and regular testing are key prevention methods.

Employing these protective barriers can significantly reduce the risk of infection.
