Hi.
There's nothing wrong with your penis--and trying to make it "straight" won't make it longer.
It's a big mistake to think that your penis has to look a certain way in order to "please" your wife.
When it comes to penises, there's no such thing as "normal." The shape of your penis does not contribute to your wife's enjoyment of being sexual with you. For confirmation, just ask her.
Some penises are completely straight, some curve up or down, and some curve to one side or the other. All of these are simply physical variations—like the difference in peoples’ noses. The only time to be concerned is if your penis curves so extremely that it’s difficult to be sexual with a partner. This is caused by calcification and usually goes away on its own. We call it "Peyronie's Condition." It's not a disease and is fairly common.
If this is true for you, and the curvature is extreme, you might want to see a urologist for diagnosis and treatment; otherwise, stop worrying and accept your penis is it is for the wonderful pleasures it can bring to you. Dr. J
You could possibly have Peyronies Disease go to a urologist.
