Brief Answer:
Infection likely.

Detailed Answer:
Hello,
Thanks for trusting us with your health concern.
I have seen the image attached. You are having a genital infection. It can be a bacterial infection- impetigo or a viral infection- herpes. In both the cases you need oral prescription antibiotics or anti viral drugs to control this infection.
To confirm the diagnosis we need to do a culture sensitivity of the discharge from the area. If it is impetigo, it will come out positive on bacterial cultures. For cold sores, you need to get some investigations like sample from the sores to identify the virus, culture analysis, Tzanck smear, antigen and antibody studies and blood sampling for antibody studies done to confirm the diagnosis.
I would suggest to get yourself examined by a dermatologist for proper diagnosis. Meanwhile keep the area clean, do daily dressing, apply antiseptic ointment like neosporin and take a mild pain killer like ibuprofen for inflammation.
Avoid any sexual contact till it is treated.
Please feel free to discuss further. I will be glad to answer the follow up queries that you have.
Wishing you good health.
Regards.
Dr. Rakhi Tayal.
