There is no connection between a bent penis and your habit of masturbation. If it were so, all men would have bent penises. The erect penis curves to one side or the other and in most cases, it is normal.
A curved penis simply can be a result of individual anatomy. If, however, your penis has a pronounced curve or bends sharply to the left or right especially if penetration is impossible or if an erection is painful you should see the urologist. You may be suffering from Peyronie’s disease where scar tissue develops in the penis. Even the majority of these men don’t have a problem in bed, although a few may have to adjust the positions they use. In some cases, however, a man may have Peyronie’s disease, a condition that can make sex impossible.
There will be no problem with penetration. There are no ill effects and do not waste your money on going to quacks or roadside doctors who will only give you sweet talk but not make any difference.
