What you are describing is acute eczema. The oozing could be secondary infection but is more likely the eczema itself. Eczema causes wrinkling (I like your doggie metaphor.) Herpes wouldn't be on both sides of the penis and also on the scroyum. The sulfa allergy has complicated the picture (and your life) but is otherwise irrelevant.
Please see a dermatologist, get yourself on topical treatment, and get a proper diagnosis, the relief of appropriate treatment, and the reassurance to help you stop worrying about STD's.
Take care.
