Most people with trichomoniasis have no signs or symptoms. However, symptoms may develop over time. When signs and symptoms develop, they are different for men and women. In women, trichomoniasis signs and symptoms include: 
A large amount of a thin, often foul-smelling discharge from the vagina — which might be clear, white, gray, yellow or green
Genital redness, burning and itching
Pain with urination or sex
Discomfort over the lower stomach area
 In men, trichomoniasis rarely causes symptoms. When men do have signs and symptoms, however, they might include: 
Itching or irritation inside the penis
Burning with urination or after ejaculation
Discharge from the penis
