Dear Dr,
I had a protected intercourse (condom) 1 day ago. However i had a small cut on the penis 3 days old, caused by shaving, which i thought healed. I noticed today that during the intercourse probably a small piece of skin, probably not healed completely has been peeled of the small wound, there was no blood. As that cut is at the lower part of penis and not covered by the condom i am very worried that there is a potential if the person i was with had HIV, i might have been infected via vaginal fluid. Should i worry, is there a possibility that i have been infected in this particular case, and how soon can i do the test to confirm or no, if needed.
