white spots on penis head and rim, seen clearly when rubbed to be precise when masturbating. after shower it's not so apparent. been here 3-4 months. no pain, itch or any other symptom, just a color. very uncomfortable with it. also never had intercourse except oral sex few months before it showed. also i think it's not getting of because of continous masturbation (i mean never had a pause of 3 or more days).
