Is it possible to have oral sex if you are infected with trichomonas?

To @Ania: Infection occurs mainly during sexual intercourse with an infected or carrier person. Less commonly, infection can occur through the use of the same towels with the patient or the use of public toilets, swimming pools or saunas. It is also possible to transmit the infection from mother to child during childbirth. If you are afraid that the infection has not been cured, you can do a home test, which you can buy at the pharmacy. Here you can compare the prices of the test and order the test with home delivery or collection at the pharmacy: https://www.gdziepolek.pl/produkty/112550/test-t1-szybki-test-antygenowy-na-trichomonas-vaginalis-rzesistka-pochwowego-test/apteki

Can caressing the penis to a partner with the mouth, tongue and hands also lead to infection?

Is it the case that after a month of treatment with the drug metronidazole, which I use 2 times a day, trichomonas will not disappear completely, or if so, can you then have intercourse with your partner without fear that the infection will occur again and trichomonas will return?
