Sore throat after oral

So I told my bf that deepthroating him gave me a sore throat now he’s being awkward and doesn’t want me to give him head bc he doesn’t want me to get a sore throat. He still doesn’t believe me that his dick could cause a sore throat but I feel like it did bc it’s really big and he was pushing my head hard while I was sucking. I feel like I shouldn’t have said anything, idk what to do or say to him. I told him I don’t care if it happens again because I really want to go down on him. What should I do or tell him ?
