More HPV Questions?

so I've heard condoms are only slightly effective, because it can transfer skin-to-skin. I thought that HPVs that could xfer to skin were not the ones that affected the genital area? Even so, if you used a condom but were careful to no insert any part that wasn't covered, would this decrease the risk? What about the scrotum? Can that skin get the infection? If it was to, let's say, 'slap' against the girl?

One more:

If the girl had 'high-risk HPV,' in which she could literally see the legions(not sure on my terminology), but those went away (she cannot see them anymore), does that mean, for the most part, that her body is fighting it off and/or it is gone?
