Yes. I suggest that you apply no active medications to the area, that you wash the area gently and apply only moisture lotion, and that you forget about it. Such redness has no significance. If proof was needed, the biopsy provided it. I'm not sure why you thought a swab would be a better diagnostic tool, but a biopsy is much more definitive. So you don't have yeast or fungus or skin cancer or an STD. That leaves minor, superficial inflammation, no doubt left over from a previous irritation of some sort. This sort of thing is common and subsides eventually if left alone, which is what I think you ought to do. (No need to avoid sex, by the way.)
Best.
