It does appear that you have an infection of sorts & based on your history & clinical features, it could even be a herpes simplex
infection or just a bacterial infection & a UTI (urinary tract infection
). I dont think it is anything to be concerned about but yes the antibiotics et al will help. Do some warm saline gargles & make sure you drink plenty of oral fluids. Do take a regular antipyretic
as per your body weight to keep the fever in check. Do run some blood tests for herpes 1 & 2 in a week or so preferably both IgG & IgM variety. Oral sex
while realtively safe, does also constitute unsafe sex & can lead to aquisition of STD's more so if the fluids are contaminated with or admixed with blood or blood products. Am assuming you know the sex partner & can monitor his/her well being. I dont see the shaving of the region linked to your current symptoms. All the best & do hope you recover soon & do practice safe sex!!
