Could I only get Trichomonas from having sex with someone who has had sex with some else that is infected?

I was checked for STDs just under a month ago and everything came back normal. No STDs. I went into the doctor yesterday and was told I might have Trichomonas now. Does that mean my boyfriend cheated on me with someone who was infected from the time that I was last checked?

To further answer your question about whether your boyfriend cheated between the time you got tested or not..... Most often, trichomoniasis is NOT tested for during a routine STI/STI screening.... So, it's VERY likely you had this previously. You can double check by asking the clinic or your healthcare provider which specific STIs/STDs you were tested for.

That being said, Trichomoniasis is generally considered to be a sexually transmitted infection (STI), but it can be picked up non-sexually, too: warm, moist environments, such as jacuzzis, public baths, toilet seats, and used towels, can sometimes host and possibly, though rarely, transmit the organism. So, this is a consideration, although, the odds are this was sexually transmitted.

In terms of cheating, men often exhibit and experience NO symptoms at all or very little symptoms which are not noticeable to them.... So, it's also possible (if you got it from him), he's had this for a little while now and didn't know - this can all depend on how long your relationship has been, what kinds of sex you are having and if you have previously used protection.

Unfortunately, there's no definitive answer I can give you aside from advising you to consider all of those factors. Hope this helps better answer your question! :-)

Hi Anon,

According to the CDC, trichomoniasis is transmitted through sex and, "It is not common for the parasite to infect other body parts, like the hands, mouth, or anus. "

Although symptoms are not always present, female symptoms include: 


  • A foul-smelling, greenish-yellow discharge from the vagina (often in large amounts)
  • Irritation, itching, and/or soreness in the vulva, perineum, and (less often) the thighs
  • In severe cases, inflammation of the vulva and perineum
  • Red spots on the vaginal walls and surface of the cervix
  • Pregnant women who are infected with trichomoniasis may have premature or low-birth weight babies


You said that your doctor said that you Might have trichomoniasis. Although a conversation with your boyfriend may be in order, make sure to get a proper diagnosis and even a second test if it's up in the air.
