Yeah. In my case.....I was healthy. Maybe they were there but might never had effected me like they did. My ex had ulcers (h pylori). He has anxiety disorder, which I believe is gut related. I was given a shot of his bacteria and parasites each time we were intimate. Pathogens love the prostrate gland and h pylori is in saliva and the prostrate, so I was doomed from the first kiss, and he is a nice guy. Sad.
