Why do i have a strong odor down there after boyfriend and me have sex?

Doctor can evaluate: If there is a bad aroma from the vaginal discharge, there may be bacterial vaginosis or other problems. A primary care doctor or an ob-gyn doctor can evaluate. A couple can also use condoms, because then all that semen won't be inside the vagina. The semen can alter the normal ph and lead odors and increased bacterial problems in some women.
