Orgasm Basics
Obviously, there are some fundamental differences between orgasms in men and women, just based on anatomical design alone. But there are many universal orgasm basics that apply to everyone. During actual orgasm, the main physical sign is muscle contractions. There will often be a marked increase in heart rate and blood pressure.
Karezza is a term used for the technique of learning to control the orgasm response using various techniques including breathing routines and finger pressure. It is sometimes also used as a general term for Tantric-style sacred sex. The term was coined by Alice Bunker Stockham, a doctor and author who is considered a female pioneer in Tantra.
Biological Response
Essentially, there are three anatomical systems involved in the biological response to arousal and orgasm. First, there is the muscular element, which is the most noticeable due to the telltale muscle contractions associated with orgasm. There is also the circulatory element involved when blood rushes to the genital area, breasts, and other aroused parts of the body. Lastly, the neurological system is also involved, because arousal causes a rush of hormones and other chemicals to flood the brain. It is actually somewhat shocking to realize all of the work the body must do in order to have an orgasm, isn't it?
Tantric Orgasms
Tantric teachings address two different types of orgasms: the physical variety and the spiritual one. This second type of orgasm is also referred to as a “heart orgasm” or “energy orgasm.” Ideally, a person achieves one ultimate orgasm that combines both physical and spiritual bliss, leading to an amazingly powerful state of consciousness. Tantrics believe it is only then that you can use lovemaking as a way to transcend into a higher spiritual place.
