Worried about HSV genital infection. Had 30 sec, of oral performed on me. Two weeks later got two basically flat PAINLESS red lesions on upper shaft of penis 3/4 inch apart. No fluid and one had a slight shallow indentation to it and look shiny. One stayed red 2,5 days from the time I saw it the other 3.5 days. Could feel slight thickness under them. What could they be?
