I masturbated for an excessive amount of time (2+hrs) a few times a couple of weeks ago. At the time I was using baby oil. I recently noticed some very very tiny white spots on my penis, mainly mid shaft and top of the shaft (not on the head of the penis). I m a little worried and wanted to see if there s anything I could find out in regards to this. I haven t had any sexual partners since August last year and no other sexual activity (The person had been tested and was clean). I am STD free, so that is ruled out. I was wondering if maybe I ve caused some kind of a skin reaction due to too much repetitive motion or maybe the baby oil, used for a prolonged amount of time, has caused some kind of skin reaction? Any help or information would be greatly appreciated! Thanks :)
