These bumps appeared about three weeks ago on my shaft, any help?

@taxablequestions, I would start with your primary care doctor. This may be something as simple as genital warts https://www.mayoclinic.org/diseases-conditions/genital-warts/symptoms-causes/syc-20355234

You should be seen by a doctor.

@taxablequestions a dermatologist, perhaps …? In Canada, one has to be referred to a specialist by a GP.

Dermatologist for sure. Likely viral and should respond to topical treatments. Protected sex as they are presumed to be transmissible.
