Often we contemplate an intimate partnership with a person who is not necessarily our best friend. This friendship on a deep and intimate level is probably the most important ingredient is a lasting relationship. A friend can be your partner when you look beyond the mere physical attraction and see deeper into their soul. The soul connection is more than just a hot sexual attraction. Sex can be an important ingredient, but to sustain the relationship over a period of time, one needs a partner they simply like to be with. When two people can be in the same room feeling good about themselves and their partner, this friendship element can grow and strengthen. We would say, being you intimate partner's "best friend" is essential.
