can eczema be aggravated by any stds?

hi,

i have eczema on my arm. recently, my eczema is worse, it got really itchy and red. it now looks like many pimple like bumps on it. my last sex was an unprotected oral sex and heavy petting which is over 10 months now. i had this eczema on my arm before i had the sexual encounter but it was very mild. so my question is can any std or even hiv cause eczema to be aggravated or is there a possibility that std rashes can be formed on eczema because the area is already weakened by the eczema.

anything you could have gottn from your sexual exposure 10 months ago would have nothing to do with your arm.
