Welcome to HCM,
As you always used condom, there is no need of testing yourself for STD's &/or HIV
But, if you will get yourself tested for HIV, anxiety
about possibility of HIV infection will be removed.
Test for HIV is available free of cost at all Government District level Hospitals.
As you don't have any signs & symptoms of STD's, test for HIV only will be sufficient.
You are not at risk.
With good wishes,
