[|Human|] After oral sex I noticed a small black mark on the head of my penis which I presumed to be a blood clot. I have had it for the last two days or so and it is still apparent after this. How long should it take for it to disappear? and should I see a doctor if it persists? Also could I take the matter into my own hands by popping the clot with a sterilised pin or would that be unadvised? Any advice would be appreciated.
[|AI|]  Degree understand your concerns went through your details. Please do not do any sort of interference without a doctor advise. The black spot could be anything from a simple mole to a blood clot. Blood clot takes around 15 days to 30 days to disappear. If it is herpes like blisters or any other infections you need the advice of a dermatologist. To be on the safest side, please consult a dermatologist. Take care.
