Red odorous bumps looks like pimples under penis head partner had cancer causing HPV but treated could she give me genital warts? Or is it yeast inf?

HPV or Yeast. The cancer causing strains of hpv differ from those causing genital warts & someone can acquire more than 1 strain and pass it. It may also be dormant for some time before the warts form.Yeast may form an irritating site on a genital surface but i've never seen it cause pimple like structures. Hpv can produce quite a foul odor.
Need to be seen. This is probably an infection -- several come to mind, including chancroid -- and your physician needs to see it.
