Thanks for posting your query at DoctorSpring.com
I can understand your concern.
You seem to be having yeast infection with eczema. It happens due to conditions of heat and humidity and can occur after a sexual exposure.
I would recommend application of cortisone cream mixed with clotrimazole cream twice daily for a week.
That would help in resolving the rash.
Feel free to discuss further,

Thanks for your reply
It doesn't seem to be std like herpes.
It looks like a yeast infection as i mentioned. I would recommend that you visit a dermatologist if the condition doesn't start improving within three to four days of application of the creams i mentioned.
