I'm scared to have sex because of phimosis. is there any hope for me?

Sure: Have a circumcision, be cured, and never have to fool with this problem again. You will feel hopeful and cheerful knowing foreskin problems can never bother you again.

Get phimosis fixed: Mild phimosis may respond to prescription strenght steroid cream otherwise a cirumcision or prepucioplasty (foreskin retaining surgery) will take care of your problem. Bonus will be a clean penis when you wash it.
