i was giving my boyfriend oral sex last night and i could taste blood in my mouth at first i thought it was my mouth but when i looked he had blood in the end of his penis,  he went to the toilet and no blood came out and also masterbated and everything was fine.  what could be the problem is it serious thanks
helloThanks for query. You have noticed blood from the penis of your boyfriend while giving him Fellatio (Oral Sex). This could be mostly from and due to trivial injury to his frenulum which is not noticed. Ask him to clean his genitals with warm water twice daily and to take broad spectrum antibiotic like Cefuroxime along with anti-inflammatory Chat Doctor.
