Peyronie’s disease, which causes a curvature of the penis, usually develops after years of scar tissue buildup from rough sex, sports injuries, or other accidents that can cause the penis to bend slightly. And the natural enlargement of the prostate as you age can also reduce your semen volume, making you feel that you’re not as potent as you once were. And if you do have questions or concerns, you’re not alone. You may experience pain when urinating or when you have an erection, which can both be brought on by a number of chronic or temporary medical conditions. Grooming: People can trim the pubic hair around their penis to make it look bigger. A penis pump works by using suction to draw blood into the penis. This happens when your semen becomes tinged with blood and appears reddish in color. A reduction in blood flow may also lighten the color of the penis later in life. Sometimes, these orgasms may also feel less satisfying. Okay lets be honest here, a lot of men want to get a bigger penis so they can feel a greater sense of manhood, because society has attached a lot of our self worth as men with the size of our penises so to speak.
