Noticing green vaginal discharge can feel worrying. It is important to know that changes in vaginal discharge can have several possible causes — not all of which are related to STIs.

Noticing a painful lump in the groin after sex can understandably cause worry. It is important to understand that a painful lump in the groin after sex can have a number of possible explanations.
Noticing white spots on the penis can understandably cause concern. However, white spots on the penis are remarkably common, and in many cases they are entirely harmless.
Many people wonder whether it is possible to contract an STI from oral sex, particularly when giving rather than receiving. Several infections can be passed through oral contact with the genitals, anus, or surrounding skin.
Concerns about whether you can get an STI from receiving oral sex are more common than many people realise. It is a question that often arises after noticing unfamiliar symptoms or wanting to understand sexual health risks more clearly.
Having no symptoms after unprotected sex can feel reassuring, but it does not necessarily mean an infection has not been transmitted. Many STIs are known to present with mild or no symptoms at all.
Many people assume that without ejaculation, the risk of sexually transmitted infection is eliminated. While ejaculation can increase risk, skin-to-skin contact and pre-ejaculatory fluid can also play a role.
Waking up with unexpected symptoms the morning after sex can be unsettling. It is important to recognise that symptoms appearing within hours of sexual contact are rarely caused by an STI.
