How does a girl know if she’s had an orgasm?
Orgasm is the peak of sexual arousal when all the muscles that were tightened during sexual arousal relax, causing a very pleasurable feeling that may involve the whole body. During orgasm, many women’s heart rates skyrocket, their breathing quickens, and their blood pressure rates increase. Muscles throughout their bodies spasm, especially those in the vagina, uterus, anus, and pelvic floor. During orgasm, chemicals called endorphins are released into the bloodstream. They cause pleasant sensations to ripple through the body, and they also make many women feel happy, giddy, flushed, warm, or sleepy.
