Orgasim

Is an orgasim when a woman comes more than one time or when she gets hot and overwhelm with emotion

Actually no. Orgasms are not just about women but about men too.
It is something that comes after sexual excitement, it is a strong feeling of pleasure and joy.
Orgasms help release sexual tension.

In women, it is accompanied by rhythmic muscle contractions and feelings of joy and in men, it is followed by ejaculation of semen from his penis.

How old are you? Are you male or female? Have you ever touched yourself at the specific way and felt nice?

An orgasm comes after stimulation of certain body parts, most often these are penis in males and clitoris and vagina in females. However, there are other parts of the body then could be stimulated to lead to sexual excitement which is after some time followed by an orgasm.
If you have any other questions, feel free to ask

orgasms are for men and women and occur when someone is sexually aroused to the point where they reach the peak and is usually followed by a weird feeling of exhaustion that was not expected (exhaustion usually occurs in guys) that's also why some guys fall asleep right after sex, because the orgasm took enough energy out of their muscles for them to remain awake.
