I had sex with a csw on 14 apr which is 10 days from exposure. From few days ago(7 days from exposure), my chest neck and arms appear pimple/rashes and it is getting more. i am worried i am infected by hiv/stds. can anyone tell me why are those rashes and pimples appear? previously there is no outbreak of pimples or rashes before on my body. i am worried i am infected. Btw i have no symptoms of fever,flu,joint/muscle pain.
1) what causes those pimple and rashes?
2) Am i in the risk of getting stds?
