Hi indigo,
The very fine grainy lumps are called filiform papillae and the larger dome-shaped ones fungiform papillae. The filiform papillae are responsible for the rough surface texture and touch appreciation while the fungiform papillae play a role in taste perception. They both play a role in forming a bolus of food for swallowing.
In spite of the increasing popularity of oral sex, oral warts are quite uncommon and I cannot see any evidence of warts in your photos.
Adhari

I agree with Adhari, but I do signs of oral thrush, you could get a oral gel for that plus 1 fluconazole tablet.
