pain in the A**.. ....sorry!!.....
In India, its pain in the pain to queries related to STD'S especially to GP.
Any other alternative or test?
I agree with jagz, go to you GP and they can direct you to the right place...
you can go to your own GP or there is clinic that will test you, where i live we have a clinic called the brook. but try googling STD/STI clinics.
sorry hope this helps
