Physical intimacy forms a vital part of romantic relationships, marital or otherwise. Going by the general hierarchy of human needs, the drive for sex is one of the basic urges of a human being that needs to be fulfilled before moving on to higher level needs, which include security and companionship.
Sex in a relationship is very important because:
1. It ensures the overall satisfaction of both the individuals in the relationship.
2. It helps in forging a deeper emotional connect with the partner, thereby, establishing trust and understanding.
3. Sexual intimacy helps in establishing a rather firm relationship base, thus facilitating a stronger psychological bond.
4. Sex helps both the partners acknowledge the worth of the relationship, even more. Since, there is more clarity and transparency, sex helps both the partners come absolutely clean in terms of what they want from the relationship.
Foreplay helps in establishing trust in the relationship by letting the partner know that the other wants to stay with him/her and it is not the act of sexual intercourse that is only important. The lack of sex in a romantic relationship reduces the psychological wellbeing of both the partners and their emotional and physical satisfaction and takeaways from the relationship.
