An integral part of foreplay is performing oral sex on a partner; it is probably the most important step in becoming comfortable with your lover’s body. Foreplay can devolve into several playful techniques of erotic exploration, but oral sex both functionally and emotionally enhances the event. It allows us to feel closer to our partners, because we have surrendered a small amount of self-control by exposing a vulnerable body area. At the same time, the egocentric experience that we undergo when receiving oral gratification can be an enlightening one for those of us who are more reserved.
