Hello,
Sore throat with fever is indicative of infection. You are suggested to visit ER, get physically examined & get swab test along with culture done. For fever & pain take
Acetaminophen (Tylenol) & gargle with warm saline water 2-3 times a day. You can also use
Listerine water for gargling.
Since you took your Bf's ejaculation into your mouth & throat you may need antibiotics & antivirals. Get STD tests done since you are also feeling fatigued. Get treated at the earliest.
Unless you know your partner is HIV negative it is advisable not to indulge in oral sex cause it makes you prone to get STI. Avoid taking semen in your mouth if you have small blisters, cuts, abrasions, sores around the mouth,
throat infection or lesions in the
esophagus through which infection can reach the blood stream.
If one has STI (Syphilis, gonorrhea) in the throat and he performs oral sex, you can get the infection since semen is easily digestible.
Hope I have answered your query. Let me know if I can assist you further.

Dr. Nupur K, General & Family Physician
