Can one partner have trickamonis and not give it to the other even though two been sexually active?

It is possible for one partner to have trichomonas and not transmit it to the other partner, even if they have been sexually active. This is because the transmission of trichomonas depends on a number of factors, including the amount of the parasite present, the frequency of sexual contact, and the use of condoms. Additionally, some people may be more susceptible to infection with trichomonas than others.
