I just got rid of a yeast infection.my foreskin used to be retractable but it seems like it has tighten so is this normal?

Phimosis...: ...is the medical term for a tight foreskin that cannot be retracted over the head of the penis. If tighter than average but not abnormal, phimosis can then develop from infections or inflammation, eventually to a point where retraction is difficult or impossible, and sometimes dangerous (impaired blood flow to penis head). See a urologist soon to discuss circumcision or other remedies. Good luck!
