Suggest Treatment For Tight Foreskin And Curvature In Penis

I have been masturbating in face down position for a long time. But when i first slept with a girl i was not able to have an proper intercourse but when i used a condom it was fine. Recently i got to know that masturbating in face down position is not good so i want to do it the conventional way but am not able to pull my penis skin down and plus my penis is bend.
