Most curved dicks are the result of how you masturbate. The penis's soft tissue can be likened somewhat to memory foam in that, if its erection is habitually bent into a certain position, it will "learn" to assume that same position when erect.

For example, if your penis now curves to the left, this is probably because you masturbate with your whole right hand around it and squeeze too tightly so that the pressure exerted on it by your fingers bend it to the left. If you are left handed, this technique results in a curve to the right; and, if you masturbate with your palm underneath it, your penis close to your belly, it will acquire an upward curve. The more you literally "choke the chicken," the greater the resultant curve. The only curve that is usually normal is the downward one, which is usually the result of an unusually long penis coupled with insufficient **** flow into it when erect, causing it to droop.

Masturbation-related curves can quickly be straightened out by simply reversing hands for a while until the curve is removed; and then either alternating hands in the future or using only the fingers. Grasping the entire girth is unnecessary, since the erogenous zone that causes orgasm and ejaculation is on the underside just below the head. This is the only spot that rewards stimulation.

Elimination of abnormal curves is recommended, not only because women are most impressed by "hard and straight," but also because when anyone "in the know" sees a curved erection they get an immediate mental image of you desperately whacking off. Not the best first impression
