Almost everyone has some feature of their body that they are less proud of. If that's not the case, it will be in time as bodies deteriorate over time. A loving spouse will overlook those self-imposed "flaws" that cause us such embarrassment. Sexual function is much more important than appearance. And there are treatments to help with function. Don't despair.
Please do not let embarrassment prevent you from being close to your wife. She married you, she will not reject you for something like this.
A slight bend is normal. A severe bend that interferes with sex is termed Peyronies disease caused by scar tissue, usually from a trauma. Scar tissue doesn't grow and stretch, so the penis bends at that point away from the normal side which does stretch and grow.. There are injection and cream treatments to break up the scar tissue, but one should not expect a perfect cosmetic outcome. The goal of treatment is to restore sexual function if that has been compromised due to loss of erection function or pain. It's best to check with a good urologist if your sexual function is compromised. Your condition is not unusual but not often discussed.
