Hi XXXXXX,\rWelcome to XXXXXXX forum.\r\rAs per there is no evidence of STDs in your wife, it appears to be safe to swallow or drink vaginal fluid.\rA woman's vagina is acidic on the pH scale to counteract bacteria and other harmful invaders and it will give sour feeling on ingestion.\r\rVaginal secretion are under control of hormonal response and massive secretion occurs during sex and orgasm.\rIts personal preference to ingest vaginal fluid or not.\r\rShe should avoid frequent washing of vagina with water and soap as this will remove protective mechanisms of female genital tract and may predispose to STDs i.e. candidiasis and others.\r\rThere also appears to be high chances of Herpes infection as virus of herpes remains in dormant condition in nerve fibres of affected site and may spread to sex partner.\r\rIn such cases, disease may spread to you.\r\rHope that helps.\rLet me know your other query.\rTake care,\rDr. Mayank Bhargava\r
