After vaginitis is cured, if there are no corresponding clinical symptoms and the pathogenic bacteria that cause vaginitis have turned negative after laboratory tests, intercourse is allowed. The main reasons why you should not have intercourse during vaginitis are: 1) the vaginal mucosa becomes congested and edematous during vaginitis, so if you have intercourse, it will aggravate the symptoms of congestion and edematous, which will lead to the aggravation of clinical symptoms; 2) intercourse is not recommended because it will bring the medication for vaginitis out of the vagina, which will reduce the effectiveness of the medication. In addition, even if you have intercourse after vaginitis is cured, you should pay attention to the hygiene of intercourse, especially if the male partner is circumcised, it is recommended to turn up the foreskin and clean the foreskin before intercourse to reduce the possibility of vaginal inflammation.
