The fever could mean nothing, or it could mean something. Do they itch? If so it could be a yeast rash, heat rash, allergic reaction to soap, herpes, warts or a million different things. In any case I'd definately see your doctor to find out what's going on.

The laws vary from state to state upon your privacy issues. You should be able to get an appointment with your GP with an explaination of a "rash" and go from there. Perhaps planned parenthood can help or a woman's clinic in your area.
