FACT! But . . . not a serious one. The correct medical term for “blue balls” is vasocongestion. This happens when blood builds up in the testicles and/or prostate when a male gets aroused (“turned on”) but doesn’t ejaculate. It is often accompanied by a cramp-like ache and pain or tenderness in the groin area. While this can be uncomfortable, it is not a serious condition and is not an excuse to pressure a partner into sex. There are two ways to get rid of this problem–a guy can masturbate until he ejaculates, or just let the feelings of arousal go away on their own (which they will). It should be noted that girls can have the same pain and discomfort from getting aroused and not having an organsm as well.
