Hello It is not clear in your history that whether these papule are one or in multiple in number . May be ulcer or pustule , so it is very difficult to establish any diagnosis merely on the basis of this short history . But one thing , I can say that these papule or pustule are not a sign of HIV. However , these signs may be due to STD , these include : 1 Human papillomaviruses, as this is most common among STDs after syphilis and gonorrhea ,but your signs are an indication of human papillomavirus . Diagnosis can be confirmed by smear from these pustule or papule. 2 Donovanosis , ulcergranulomatous :most common type , painless beefy red ulcer . Diagnosis can be confirmed by direct visualization of organism in macrophages . 3 Chancroid , another one such reason. However , there are so many STDs diseases as may be due to fungus infection . So in my opinion physical examination will clearly establish the diagnosis . So consult a physician / dermatologist and get his opinion. Good luck.
