👉 Penis fluid, also known as pre-ejaculate or cumulus fluid, is a clear, milky substance produced by the corpora cavernosa and corpus spongiosus tissues of the penis during sexual arousal. It serves multiple functions: it helps lubricate the penis for easier penetration, maintains an optimal pH level to protect against infections, and carries sperm from the epididymis into the urethra, facilitating fertilization. The composition of penis fluid includes water, proteins, fructose, and various enzymes, which together create a nourishing environment for sperm. This fluid is typically released before ejaculation and diminishes as arousal subsides, though its presence can be a natural indicator of sexual readiness.
