An orgasm refers to the sudden release of sexual tension that has accumulated as a result of rhythmic contractions in muscles in your pelvic region that produces an intensely pleasurable sensation that is immediately followed by relaxation. While an orgasm is typically associated as a sensation felt in the body, it also has a psychological component to it relation to pleasure as well as abandon, where the mind is solely focused on a personal experience. An orgasm may also be referred to as a climax.
According to some research, an orgasm occurs as the third out of four stages during sex, following the plateau and coming before the stage of resolution. Some researches though follow a model where the cycle for sexual response includes only three stages: desire, excitement, and then orgasm.
While an orgasm is expected to be a part of the sexual experience, it varies from one person to another. Sometimes it can be explosive, with surging sensations that wear people down, while other times it can be milder and more subtle, less intense though still very satisfying. These variations in orgasms are attributed to certain factors, both physical and psychosocial. Some of the factors that can affect what kind of orgasm you have include mood, fatigue, and expectations, as well as how long ago your last orgasm was.
