An STD, commonly known as a sexually transmitted infection, can be contracted by oral, anal, or vaginal intercourse, as well as genital touching (STI).
STIs and STI symptoms can affect anyone, regardless of marital status or sexual orientation.
It's not enough to assume or hope that your partner doesn't have a STI; you need to know for sure.
Condoms are quite effective at reducing STD transmission when used appropriately. However, no treatment is perfect, and STI symptoms aren't always visible.
Consult a doctor if you suspect you have STI symptoms or have been exposed to one.
Additionally, notify your partner or partners so that they can be assessed and treated.
