I get freq.bv,uti,and yeast infections. my bf has had nasty odor on penis for months now. even directly after shower it smells. did i infect him?

Circle never broken: The BV circle of infection is obviously never broken as long as you are the only one being treated and intercourse continues. Have your boyfriend see a MD soon and you should refrain from sharing that "nasty odor" item until you are both cleared of any infections including STD's.

Probably unrelated: Odor similar to bacterial vaginosis can occur whenever there is overgrowth of anaerobic bacteria (i.e. don't require oxygen). This can happen in any closed space, e.g. under the foreskin (probably your partner is uncircumcised). His odor probably is unrelated to your BV or other infections. It should clear up if he will retract the foreskin and wash with soap & water 3-4 times daily.
