I’ve only had 2 partners my whole life and it seems every time I give my at the time girlfriend’s oral sex, I always end up with tonsillitis. I thought it was an STD or an STI but every time before sex, I make sure they are tested and show me proof and they always come back negative. Why is this happening? Anyone else experiences this? I don’t have the funds to keep going to the doctor or hospital. Am I allergic? Please help me.
