Dear Doctor,
In the last one month I've had two encounters with two different escorts. On both ocassions, I wore a condom while receiving oral sex and during vaginal sex. However I did perform unprotected oral sex on both women. Neither had any visible lesions or sores in the genital area. What are my risks for catching HIV or any other STDs ? The second encounter was last week when I had a slight cold which has still no gone over, I still have a sore throat. Please advise me on how long I should wait before an STD test. Thanks.
