Could I be having prodrome for my initial herpes outbreak? I had sexual contact over 30 days ago. No fever over the last few days. Genitals tingle

Possible. Did your sexual partner have herpes? If so, the symptoms you now have could be related. Local pain ; itching, plus fever, headache, malaise, myalgias, and tender lymph nodes are more usual than "tingling." average incubation period after exposure is four days, but ranges from two to twelve days. See your doctor -- viral cultures can be done on any visible sores.
