Sexually Transmitted Infections

What Are STIs?

STIs (Sexually Transmitted Infections), also known as STDs (Sexually Transmitted Diseases), include bacterial, parasitic, and viral infections that are passed between sexual partners. STIs can be transmitted through infected blood, pre-cum and cum (semen or vaginal fluid), and sometimes through skin-to-skin contact. They can be passed between all people regardless of their sex, gender, the partner(s) they have sex with, their age, class, race, ability, or any other aspect of their identity.

Bacterial and parasitic infections can be cured, but viral infections cannot—although they can be treated and managed. It is possible to have more than one STI at a time (co-infection), and to get the same STI more than once (re-infection). Many STIs and other infections can lead to cancers and other illnesses if they are not treated.

There's no way to know your STI status unless you get tested. Taking care of your health includes regular STI testing, and using barriers and lube for sex.
