What does a man's penis look like? What do testicles look like? What does a circumcised penis look like? What does an uncircumcised penis look like? Well, here is the long and short of it. They are all different but share the same general compononts. Every penis has a head and a shaft. The head looks like a helmet with a little hole in the top of it. (The most sensitive part of the penis is the the edge of that little helmet, all the way around. If you want to make a penis very happy, rub something wet up and down over it for a while.) An uncircumcised penis has a flap of skin covering that little helmet while a circumcised penis has had that flap of skin surgically removed so that the head remains constantly exposed. Below, you will see examples of both. Click on each thumbnail below to get a better view.
The scrotum is the bag you see in all these photos under the shaft of the penis which contains the testicles. Slang term, "balls". The scrotum serves two functions. 1. Regulate temperature of the testicles. 2. Protect the testicles during sexual activity. The scrotum will relax and allow the testicles to hang low and away from the body when the testicles are hot and need to cool down and then will draw up close to the body when the testicles are cold and need to warm up. But during sexual activity, the scrotum will draw the testicles up close to the body during the final stages of arousal and prior to ejaculation. Ejaculation does not normally occur until the man is aroused enough for the scrotum to draw up close to the body.
