You really should see a doctor as soon as possible, especially if you are having chills and a mild fever. Perhaps the bumps could be the start of a venereal disease such as herpes virus (see the following website):

I will tell you this: When I was in my 20's, I had similar symptoms, and it turned out that I had Shingles! The lesions or bumps were painful, and I also had discomfort urinating and a slight fever.
Shingles is a similar virus, in fact you can get it from someone who has Chicken Pox. Please see the following website: http://www.fda.gov/fdac/features/2001/301_pox.html
You would be best to go to the doctor's or the local emergency room, if they get much worse, or if you do not feel better by tomorrow. A mild fever does not always signify a mild disease. In adults, any mild fever can sometimes be something to really pay attention to.
You also, may have lesions from the rough sex, and it may be raw in those areas, and you may have gotten some kind of infection, either viral, or bacterial, that is causing your symptoms.
God bless, and take care!
