Hello,
I understand your concern.
I am Dr. Arun Tank, infectious diseases specialist, answering your query.
In my opinion you should not worry.
Protected sex never causes
STD .
It may be sensitivity due to latex of the condom.
Keeping only hygiene Is the only thing requires to taken care of. Maintenance of hygiene only will cure your infection within week.
Avoid sexual intercourse till your part gets clear.
Avoid using condom also till this time.
Wash the part with clean water daily while you bath.
I will be happy to answer your further concern, you can ask me on bit.ly/DrArun.
Thank you.
Dr Arun Tank
Infectious diseases specialist.
