Dear Glitterstr,

"Cum" is a slang expression that as a noun usually refers to semen (also known as ejaculate), which is the fluid that contains sperm that is ejaculated during sexual excitement by men. Semen is composed of seminal fluid, which nourishes the sperm and helps them to move. Cumming, or coming, is the act having of an orgasm. In men it's also about ejaculating semen.

To cum or cumming also refers to women's and girls' orgasms. An orgasm is a series of muscle contractions all along the penis or all through the vagina, clitoris, and pelvic area. An orgasm releases the body tension that has built up through sexual stimulation. In some women, a clear fluid spurts out of the urethra during sexual excitement or orgasm. This is also called ejaculation, or cumming.

Hope this information helps!

Take care,
