Could anal fingering feel good (for men) without touching the prostate? And other questions

Heyo ppl, i have a few questions for my m/m smut

1-i heard that when you press down on the peripheral nerves near the whole it feels good even if you dont touch the prostate, is that true?

2-is it possible for a man to have multiple sweet spots that he enjoys most?

3- Ill add more questions if I remember
