The others say I woke up and found a purple/blue mark on the head of my penis, it was ever so slightly sensitive. It basically looked like a penis bruise /cuntusion. I went to my public health clinic (which in my country can be extremely incorrect in diagnosis (like my grandmother died due to two years of mis-diagnosis kind of wrong)) and they assured me it was just a basic bruise. Problem is that as of recent there has been a concerning slime/discharge from that affected area which is concerning to me (not from the tip but the actual "bruised" area) . Note I have been sexual with solely one partner for over 4 years and though posssibilities do exist I doubt it is from this person.
