Typically, trichomoniasis shows up in four to fourteen days after infection. It can, however, have a latent period in either men or women. Three years with no symptoms is highly doubtful. If you have been having sex with her, it is likely that you have been infected. In some men it disappears on its own and in others, they can become carriers for quite a while. It is easily treated so, please. seek treatment. I assume she is on her own for treatment.
It is transmitted in vaginal fluids and semen. Women can transmit it to women but it does not show up on its own without sexual contact.
