Been having bleach spots on my penis and burning when I squeeze my head. Got tested for chlamydia and syphilis negative. Also really smelly feces.

Need more tests. There are other infections that need to be looked for to explain the burning. Also, fragrances in anything, harsh soaps, can irritate the opening of the urethra & cause burning, as can over-scrubbing. Bleach spots may not be related. See doc again. Use products for sensitive skin (and your partner needs to, too). No fragrances, no aerosols, no alcohol-based products, no rough scrubbing, hot H20.
