If it is possible to pass other things on, it should be possible that an uncontroled infection
could be passed on as well.
myself however, each time that I had a prostate infection
or a UTI, I have never been interested in sexual contact during that time. Most of the times to clear up an infection, I was put on Cipro 500mg for about a month at a time. It could be that one would still have an infection but has started to feel well enough to no longer feel the effects of the infection.
