Hello, Welcome to HCM, Your symptoms and history is suggesting me that you may be having herpes genitalis. This is a sexually transmitted disease you have acquired this disease by having sex with the person having this disease. All type sex oral, vaginal and anal can transmit this disease and this is a very painful condition. I suggest you that you should not indulge in any type of sex till your symptoms improve.You can take oral antiviral drugs like acyclovir thrice daily, it is not going to cure but it will prevent further multiplication of virus and prevents the symptoms. You can apply antiviral ointments on the lesion. This is a viral infection which is a self limiting disease. If your symptoms are not improving you have to consult your urologist for further opinion. Thank you.
