Situations in which you should be tested for STIs

After having unprotected sex

Whenever you have sex without a condom, whether vaginal, anal or oral with a partner whose health history you don't know, you should consider getting tested.

When you start a new stable sexual relationship

The beginning of a stable love relationship is usually accompanied by greater intimacy and trust. Couples often choose to stop using condoms as a sign of commitment, but this decision must be taken responsibly.

Before they stopped using protection, It is essential that both take STD screening tests, Even if neither partner shows any symptoms. This is because many infections can remain asymptomatic for months or years, and are transmitted unknowingly.

This gesture shows mutual respect, maturity and care for the health of both.. It also allows the couple to begin this new phase in complete transparency, reducing the risk of unpleasant surprises in the future.

  • Prevents long-term health complications for both.

Even if you have been in a previous relationship that is considered “safe”, it is possible to have contracted an infection without knowing it. That's why screening is recommended whenever you change partners, especially when the goal is to build a lasting and healthy relationship.

Multiple partners or occasional sex / one-off encounters

If you have multiple partners, occasional relationships or use dating apps, the risk of exposure to STIs increases. In these cases, regular testing (every 6-12 months, even if there are no symptoms) is recommended.

When suspicious symptoms appear
