What is trichomoniasis?

Hi guys,

Today I got a call from the clinic saying that I have trichomoniasis because I was in so much shock i was so eager to hang up the phone and didn’t ask the questions I needed to.

Last year I slept with two guys within the space of a month. I need to understand how trichomoniasis could I have had it and passed it on or does this infection normal affect men first
