Symptoms that help distinguish a true orgasm from a sham:

• Breathing becomes more frequent, becomes deep and intermittent. • Before the climax, the vagina is compressed, tightly clasping the member in a ring. • Before the cherished denouement, there is always an abundant release of vaginal lubrication. • Face and neck flush with excitement, eyes close or roll back. • The body and limbs may make unusual movements that resemble convulsions. • Someone makes inarticulate sounds, others swear or just moan.
