Its three day since I visited an Asian spa, where I received protected oral sex and vaginal sex. In the middle the condom was taken off and then reapplied (no new condom was used). I am now experiencing sensitivity towards the rim of my penis and what seems to be the urethra as well. I know my risk exposure is low but I cant stop looking for signs of an STD. Is this all in my head? The issue mainly started last night after my shower and has persisted ever since...
