She might have BV (especially if it smells fishy, and especially if it smells fishy after intercourse, if you're not using condoms). She should see her gyn and get it checked out.
She needs to talk to her Gynocogist about the problem, there's probably a simple fix
The first time i had sex with my husband which was about six yrs. ago i started smell horrible. I did not smell my self but people made comments about stench and rotten meat, or feces odour. We were tested for hiv and syphillis before marriage both of us negative. One year later my feet started smelling like fungus moldly. I became very depressed in the first yr. of marriage and very sucidal. There i did not persue the cause of horrible i did mention it to drs. they dicovered i had h pylori i was treat for but still persisted.
I have since left my husband and trying to rebuild my life. So went to podiarist
(foot dr.) He treated my fungus foot infection for one year with out relief and then told me i have sexually transmitted diease. I ask my obyn if is possible she said no stds don't cause smelly feet and breath. Could some give idea if std could give me these odors and what i may have.
