Herpes or Bug bites? Please help!?

I recently noticed a white mite in the band of my underwear and a few days later noticed an outbreak of "bites". I was wondering if it is more likely to be from this insect or an STD like Herpes. The "bites" are randomly spaced around my thigh and there are maybe 7 in total. There are four on the shaft of my penis and testis; this is what concerned me at first. They are not grouped or clustered together and don't blister or burst. So is this likely to be Herpes?
