Hello,
It is mostly suggestive of
Trichomoniasis or
Bacterial vaginosis. You both need to take repeated course of
Clindamycin or
Metronidazole to eliminate this condition.
You should avoid UNPROTECTED SEX and maintain genital hygiene. Use VAGISIL cream at bed time and maintain vaginal pH with probiotics. Kindly, consult with doctor for prescription.
Good luck.
