Everyone take mind that this was about a year ago, not recent!
If it was over a year ago, why worry about it? No, you can't give a uti to him.
Wow.. not to sure how sanitary it is for him to be giving you oral while you are on your period... but hey.. whatever... UTI's can just come about.. I have gotten UTI's without having sex before.. was he tested and had gonnereah (spelling?) and that is why he is saying that is what you gave him?
im not to worried about the situation i just wanted to see if anyone else has expierienced something similar. He did not test positive he had a uti.
