Sorry I didn't mean blade infection but bladder
Maybe a blade infection or some type of ngu or bacterial infection/fungal infection, maybe a yeast infection, but generally they test for most of those in a urinalysis, but that's my experience with my doctors. Herpes I would say probably not, as it's been 20 days with no signs, it usually shows up by day 10 and rarely out to 20. Hsv1 is generally what is on the mouth and is harder to spread to the genitals, it is possible and is on the rise do to oral sex, but the information above suggests you don't have it because the symptoms are very much like a typical herpes outbreak, not the ones where it's a rash that you hear about online, as well as its very very rare to have an outbreak just inside your penis, you would most surely have sores outside as well.
