i ve been dating my boyfriend for almost a year...when we have sex and he ejaculates inside me for a couple days afterwards my urine has a really foul odor...if we go for more than week and dont have sex, the smell fades, but then when we have sex again the smell returns...i have been checked for infections and have none...there is no pain, my vagina doesnt smell, just the urine...there is no discharge...we dont use birth control or condoms as i had my tubes tied 7 years ago...
