Hi thanks for your question.
The seminal fluids contains fructose and semen which are not harmful ,however bacteria present in seminal can cause
tonsilitis and
pharyngitis.The whit thing which your mentioning could be
peritonsillar abscess .The tonsilitis and peritonsillar abscess should have resolved by one week time.I would suggest you to consult an
ENT specialist,who may take swab from your throat for culture sensitivity and may advice you accordingly.
Hope this answers your question.
