👉 Threesome fluid, also known as pre-ejaculate or cumulus fluid, is a pre-ejaculate substance that occurs during sexual arousal in both males and females. It is produced by the seminal vesicles, prostate gland, and bulbourethral glands in males, and by the vestibular glands, bulbourethral glands, and sometimes the female ducts in females. This fluid serves several purposes: it helps to lubricate the vaginal area, neutralize any acidic residues from previous urination, and contains antimicrobial properties to protect against infections. It also aids in the stimulation of sexual arousal and can enhance the experience for both partners, though its primary function is to prepare the female reproductive tract for potential fertilization.
