What is the reason for the green liquid?

Patient's question:

Not painful or itchy, like water, I'm almost scared to death. I've never been like this before. Maybe we were a bit impulsive that day and did it for a long time. Also, that day we stayed in a hotel outside. I'm afraid I might have contracted gonorrhea. I don't really understand these things, just guessing. Is this situation serious? What should I do? Thank you

Doctor's answer:

The lower body may be discharging yellow-green liquid, which could be trichomoniasis. You should go to the hospital for a routine vaginal discharge test. Trichomoniasis is a common type of vaginitis caused by the vaginal trichomonad. Clinically, it is characterized by increased vaginal discharge, yellow-green in color, rare in texture, foamy, foul-smelling, and itching in the vagina.
