Lately when my boyfriend and I have sex there is this brown discharge that comes an it doesn't come after sex it is just during. Sometimes it will have an odor and other times there is not. What is this? Could it be an STD?
WEll IF you're doin anal, it could be you know what... but i assume its not so i only thing i can think of is old period blood... still there. Or you're about to start one and the blood's comin out that didn't finish with the last period.
