STDsssss

Soooo I've been checked before just because, and my boyfriend has a UTI and he went to the emergency room to get medicine and they tested him for a UTI and STDs the doctor said the test came back as a UTI and they said it's rare for a male to get a UTI, we had sex 4 days ago and he had to pee really bad but didn't and we still had sex and he held it the whole time, and now he's asking me if I have STDs.... And I'm not sure if I should be offended or if I should be understanding.....opinions ladies
