Okay so I gave my boyfriend head last night and we both don't have any std or anything like that this morning he told me that there's a little lump he said about the size of a bean near the tip, he says it's the colour of the skin. What is this ? Sometimes when I give head the skin rubs against my teeth, not sure if that will help but he's worried and i just wanna make sure he's ok and if he need to see a doctor
