Hello, thanks for the query.
Side doesn't matter it is the simple allergy
( itching over scrotum
and penile area ).
Itching usually occurs at night time when concentration of one is towards it.
Please clean the effected area with a savlon
soap in the morning and evening.
After cleaning soak it with dried towel gently, after this use a medicated ointment after the advice of some doctor.
drugs are also useful in this condition.
Have a full course of albendazoel + ivermectin
with the advice of doctor and you will be alright.
This type of itch is normal and haven't any effect on sex life.
Good luck. Dr. HET
