Hello dear,
I understand your concern.
In my opinion the itchiness could be due to
urinary tract infection(UTI).
UTI is very commonly seen after intercourse in the initial days.
Certain precautions like washing the genitals and passing urination by both the partners before and after the intercourse prevent the UTI.
It might not be due to
allergy to latex condom because if that was the case the itchiness of
vulva is present throughout the day but not just only during the urination.
In case of any sexually transmitted infections (
STD) there can be local lesions or altered
vaginal discharge etc.
As per your information you dont have any such complaints.
So i suggest you to rule out UTI and wait and check for the urine culture report.
Nothing to worry.
Take adequate fluids upto 2-3 litres to prevent UTI.
And abstain from sex till the symptoms decrease.
And wear loose cotton inners.
Relax.It will subside.
Hope this helps.
Best regards...Dr.Srilatha
