I got something for the itch until i can see a real doctor I had a family friend who was a nurse look at it.
did a doctor tell you? or someone else? if it was someone else go to a doctor. if it was a doctor make sure you get something for it! especially if it's poison ivy...poison ivy gets REALLY itchy.
Well i found out its just a poison ivy like rash all over that from my clothes so its not an std or i was told its a sweat rash.
you need to go get them looked at. you may have an std and also crabs. does the girl or guy that you've been active with have any symptoms?
