Hi,
I discovered a small red spot, about half inch in diameter, on the base of my penis shaft. I first noticed after getting out of the pool this morning. I didn't notice earlier in the day. It is dark red or maroon in color. Their is no protrusion or pain or even discomfort. It doesn't even feel any different than the surrounding area. If it were on a different part of my body I wouldn't be concerned but because of its location I'm a little worried. I'm 63 years old if that helps. Could tell me what it might be?
