Thanks for posting your query.
After reading the complete problem, let me reassure you first that none of your symptoms are related to herpes.
To explain you simply genital herpes
manifests itself as small vesicles(blisters) which remains for a day or two and then forms painful ulcers which heals in 5-7 days of period. These vesicle can appear within 3-14 days of exposure.
In your symptoms basically you have problems related to digestion and there are no any symptoms related to skin. These symptoms also appears to be due to excessive of stress
which you have taken in your mind.
Kindly relax yourself as there is nothing related to any of the STD's including herpes. Do take care next time and always use protection.
Hope these informations will relax you.
With good health wishes
