In traditional tantra, the role of sexuality is spiritual in nature. The physical act is merely a method of reaching a higher plane of connection with the universal energy. Comparatively, neotantra practices focus on creating a spiritual connection between two individuals through sex. The differences might seem subtle, but the focus is drastically different. Traditionally, tantric sex was a means of connecting to the spiritual. Sexuality and sexual contact was considered part of a sacred rite. In Western culture, the spiritual aspects are often overlooked, with more focused placed on simple enjoyment and heighten sexual pleasure.
There is nothing wrong with increasing sexual pleasure for simple sake of enjoying intimacy between two people. However, for those looking for a deeper connection, the Western view of tantric sex often leaves out the underlying principles for which tantra was developed. While technique, breathing exercises and other aspects of neotantra bring about heightened pleasure, understanding the changes in mindset needed and respecting the spiritual origins of the practice can multiply the pleasure considerably.
