Question about facial hair?

I am a teenager who never had a lot of facial hair. I started shaving when the first hairs started to grow on my chin and had practically none on my cheeks. Now when I don't shave for a while (no access to razors or cream) I can grow a beard on my chin but I'll only get two or tree hairs on my cheeks. I think this might had to do with the fact that I never really allowed my cheek hair to grow and get thick like I did with my chin hair. I think that because my chin hair was already thick and visible when I shaved it will come back thick and visible. I am currently abstaining from shaving to see if I can grow hair on my cheeks. My question is: if I allow my cheek hair to grow to it's full visibility over the time of about 3/4 months will it come back visible faster when I shave it? Or will it take 3/4 months again until it is visible?
