The cleanest parts of the body are mucosae, Interacting with those parts in the form of douching or washing of any sort brings about many infections thant can be avoided. It is advisable to do a peripheral washing with soap that does not involve any interactions with the internal structure. This advice is given to PLWHIV so that wounds will not be infected or infect the person. I hope this was useful
Douching definitely increases yeast infections because yeast is everywhere and douching may decrease the lactobacillus which keep yeast in check.
But when it comes to sexually transmitted diseases like Trichomonas, its a double edged sword. While douching may cause imbalance with local indigenous bacteria and yeast, it also could potentially remove the trichomonas if done immediately after sex with the offending partner...
in this article, prostitutes use douching to decrease Trichomonas infections:

Abstract
Sexual transmission is the fastest growing route of HIV transmission in China, andTrichomonas vaginalis(TV) can facilitate HIV transmission and acquisition. Our goal was to determine the prevalence and correlates of TV infection among female sex workers (FSWs). This cross-sectional study was conducted in a city of Yunnan Province in southern China, with confidential face-to-face interviews and laboratory tests for TV (wet mount) and other sexually transmitted infections. A total of 734 FSWs participated in the study. The prevalence of TV was 9.0% (95% confidence interval [CI] 7.02-11.30). In multivariate analyses, adjusted odds ratios of TV infection were 3.0 (95% CI 1.47-6.01) for herpes simplex virus type 2 seropositive, 2.4 (95% CI 1.37-4.14) forChlamydia trachomatisinfection, 2.6 (95% CI 1.30-5.31) for genital ulcer, 1.9 (95% CI 1.11-3.30) for starting age in commercial sex
Since trichinosis is triggered by an imbalance in the pH levels of the vagina. So It dependent on the type or Ph of the solution used for vaginal douche so not all douches increase the infection but the douches affect on the Ph. For example: regularly eating yogurt prevents catching this infection through a healthy bacterium called lactobacillus. which promotes the growth of good bacteria in the vagina, which help restore the pH balance. I read about natural remedies which used for vaginal douches e.g
a douche solution using tea tree oil. It contains substantative antifungal and antibacterial properties which help fight the infection caused by trichomonas vaginalis. Dilute teat tree oil with an essential oil like olive or almond oil, and use this vaginal douche.
Another effective douche solution can be made using apple cider vinegar as it is also beneficial in combating the infection. Dilute apple cider vinegar and use this solution for douching. Douche the vaginal area regularly until the symptoms have resolved.
I have been researching vaginitis for the last 20 years. There is no research evidence for tea tree oil or apple cider vinegar, therefore, no evidence that the above claims are true. I know many cases in which they did nothing at all for yeast. When you are talking about a sexually transmitted disease- it is best not to give mythical qualities to things like tea tree oil and apple cider vinegar when they are probably the same as doing nothing.
Thanks so much for your answer but when I gave my answer it doesn't mean introduce a treatment for Trichomonas but for using some herbal/remedies as a vaginal douche.
