Not sure what these are but most are just plain white and some are just red with a tiny scab(?). Before noticing these, I was tested negative for HIV. Possibly from shaving too much? .
Yes, I think this is due to the shaving - probably the razor you are using is too sharp and it is taking the tops off things that are naturally present on your genitals.
I would suggest you take a 3 month break from shaving - some aftershave balms can help the skin recover.
Once initial healing is achieved leave the skin alone to recover for the remainder of the 2 months
I use razors that have been well-used on my face before I use them on my genital area, that way they are less sharp and less likely to do harm …
