Treatment
Most sexually transmitted infections are easily treatable with medication. Self-treatment (e.g. with medications that are left over from a previous illness or medications of friends or acquaintances) is not advisable – it can lead to protraction of the infection, resistance development of the pathogens, further spread of the infection, and later complications.
The treatment of sexually transmitted infections in people with HIV should be performed by specialists with particular experience in this field because interactions of antibiotics and other substances with antiretroviral therapy are possible.
Unfortunately, you cannot build immunity against sexually transmitted infections (except in the case of hepatitis A and B). That means you can contract them over and over again.
