Just to add, there are about 8 and they range in size from 2mm to 1/4 inch and they are rarely painful but sometimes itch, I do masterbate maybe once every other day but have stopped on eve I realized the sores were getting worse. I have never had contact with anything and have been using hydrocortisone and anti bacterial cream with no effect. Please help me and give me a reply, I am really starting to get worried. Thank you.
