Why is it that when we men masturbate, our testicles move to the sides and stay there like they're static? Is that bad?

When men masturbate, it's common for the testicles to move away from their usual resting position. This movement is typically due to the contraction of the cremaster muscle, which is responsible for raising and lowering the testicles. This behavior is part of the body's physiological response to sexual arousal and activity. When the testicles are stimulated or during sexual excitement, they may ascend closer to the body, while during relaxation or arousal, they may hang lower. The lateral movement you describe can happen as part of this process. In most cases, this is perfectly normal and not a cause for concern. The testicles might appear to be in a different position temporarily, but they usually return to their normal resting state afterward. If you experience pain, significant discomfort, or persistent abnormal changes in testicular position, it would be wise to consult a healthcare provider. Otherwise, this movement is a natural part of male physiology.
