A term used to describe an uncomfortable feeling in the testicles when sexual excitement does not lead to ejaculation. In actuality, both males and females can experience this uncomfortable feeling as a result of sexual pressure that builds up but is not released. It is usually described as a full feeling or an uncomfortable ache that occurs in the genitals. For males, this occurs in the testicles (balls) and for females this occurs in the lower pelvic region. There is no damage as a result of pressure that is not released, and “blue balls” is never an excuse to keep going if someone wants to stop sexual behavior.
