Your symptoms don't sound like any STD. You clearly have a generalized skin rash
; as someone else commented before me (shown below), it sounds like it could be an allergic reaction to something--and from your description, peanuts sound like a good bet. But lots of other, no
n-allergic conditions are possible. Most likely this isn't HIV, and the risk of catching HIV from any single episode of vaginal sex, even if the partner is infected, is very low.
