During an erection, the spongy tissues relax and trap blood. The blood pressure in the chambers makes the penis firm, causing an erection. When a man has an orgasm, the second set of nerve signals reaches the penis and causes the muscular tissues in the penis to contract and blood is released back into a man's circulation and the erection comes down. You can use Fildena 50 for this problem.
