AK suit, best flop or?

Stuff like these have been happening to be alot recenlty and I want to know what I am doing wrong. How can I controll the pot size well and when should I fold?
I do not have any kind of read on the villian at all.All I know is that he waited a long time when he called the preflop bet.
