I would never disapprove what a doctor told someone, especially not by looking at a low-quality photo, but in my opinion this is much more likely to be molluscum contagiosum then folliculitis.
can you upload a clearer picture? i was recently diagnosed with folliculitis there as well, and can tell you if it looks like what i have.
some better picutures are required, but to me it is looking like a classic case of molluscum contagiosum i think your GP may need to put his/her glasses.
from personal experience, doctors blame every skin rash/ lesion/ spot/ blister etc etc on folliculitis, its an easy pass off and oldest trick in the medical book, and its usually because they dont want to spend time and money on a biopsy and further investigation.
makes me angry.
