5 months ago i had a unprotected vaginal sex and 3 months ago i touched vagina of a girl then she bite me then 1 month ago i finger another girl then this december 10 my i scrub my penis in the legs of a girl near her vagina but i am sure that she's wearing a short ang panty. Then this December 19 my back is so itchy then i scratched it then they become 5 red bumps and after 1 week they become brown and when i went to dermatologist she said that is is a insect bites. My question is. This is a hiv rash? Does hiv rash show up without other symptoms? Thank you. I hope answer my question. Because when i think that it is a symptoms for hiv my body become itchy and irritating and when i scratched it they become red then disappear but there a some remain small dots. I have no fever and no other symptoms. Thank you.
