Me and my girlfriend have been having sex for about 6 months sometimes protected sometimes not we were both virgins haven't done anyhting with anybody when we meant and two days ago I noticed that right under neath my penis head, when you pull the skin down there are 4 little red dots and a red blotch about a centimeter long, can you tell me what this is, and if possible how can I get rid of it,

Only a doctor can tell you what it is and how to get rid of it, you should go see one.
