Is there any other sexual infectious diseases that cause death other than hiv?

Yes: Tertiary syphilis (late stage) can lead to death if untreated. Gonorrhea, if it enters the bloodstream, can cause a disseminated infection that can lead to death as well.

If not treated only: Most STD can be successfully treated including HIV these days and most people who take their Meds and get treated with proper follow up do not die But if not treated at all or not treated appropriately with proper follow up will die with Syphilis which is easily treatable but if not treated will go from fist to second and third stage and will cause death And rarely with Gonorrhea if not treated

Yes indeed: The most common by far is HPV causing cervical or anal cancer. Next probably is hepatitis B, which can prove fatal over time, either directly by liver damage or from liver cancer. Syphilis very rarely is fatal in adults, but occasionally causes congenital infection with fetal death (miscarriage or stillbirth). Extremely rarely, complications of gonorrhea, chlamydia, or herpes can be fatal.
