How Does Sex Affect a Couple’s Relationship

A romantic relationship is basically defined as a state in which two people have connected amorously.  But staying connected is not only achieved by going to each other’s birthday parties, consoling each other when the other one has had a bad day, or telling each other “I love you” every night. The reality is, sex is also an integral part of that romantic connection, it can actually make or break couples. Here’s how sex affects a couple’s relationship:

1. Sex Keeps Both Parties in the Relationship Healthy

It may not be true for all, but after sex, some couples feel energized and ready to take on the world. Studies have shown that this is because sex is a form of light exercise. This means, in a way, just like walking, it provides health benefits and a burst of adrenaline to those who engage in it. Apart from a better form, those who have sex on a regular basis can have the following: 

  • Reduced risk of heart disease and stroke: A study made by scientists at the New England Research Institute found that men who have regular sex are up to 45 percent less likely to develop a heart ailment. A study in the American Journal of Medicine has found that those who survived a heart attack and engaged in sex at least twice per week were less likely to die than those who did not. 
  • Lowered blood pressure: Although sex can never be a substitute for medications that lower blood pressure, it can complement them. Studies have shown there is a relationship between sex and systolic blood pressure, the top number in a test for blood pressure. 
  • Fewer chances of prostate cancer (for men): A Harvard study has found that men who ejaculate (during sex, masturbation, at night) at least 21 times a month are less likely to have prostate cancer 
  • Increased immune system: A study made by scientists at a Pennsylvania university found respondents who had regular sex produced an antibody more than those who had less frequent sex  

How is this in any way related to a couple’s relationship? Remember that a healthy life is a happy life. This means that if both parties in the relationship are healthy, they are also happy and will contribute nothing but positive energy to the relationship.

2. Sex Binds Partners Emotionally

While it is true that sex binds partners physically, it is even truer, more so, in the fact that it brings them together emotionally. People naturally let their guard down when they have sex with their significant other. Sexual intimacy necessarily results because both parties share and communicate messages, not through words, but through their love-making.    

Those in the scientific community know there is a scientific explanation for this. When people have sex, oxytocin is released. Oxytocin is also called the “cuddle hormone” or the love hormone” and is associated with emotional bonding and trust.  Oxytocin is involved in the following: 

  • Childbirth 
  • Breastfeeding 
  • Father-child bonding 

But those are not all. When the partners in a relationship orgasm during love-making, this hormone is stimulated even more.  This only means that the emotional bonding between the two engaged in sex is consummated.

3. Sex Is A Great Stress-Reliever

Sex also provides psychological benefits to both parties in the relationship. Sex, in particular, is actually a technique to manage stress. An Arizona study published in 2007 found that there was a correlation between sex and mood among middle-aged women; women who had sex with their partner were stress-free and exhibited lower negative mood and higher positive mood the following day. The study found that this did not hold true for women who ejaculated without a partner. In men, ejaculation also actually reduces the activity in the prefrontal cortex, which is that part of the brain that benefits from a relaxed state. 

The fact that sex is a proven stress-reliever further boosts the statement sex plays an integral role in nurturing couple’s relationships. This is because stress in many ways affects relationships, including romantic ones. If your partner had to sit in traffic for five hours instead of the usual thirty minutes just to get home, chances are, when he or she meets you right after, you’d be the receiving end of snarling comments. If he or she gets yelled at work, chances are, when he or she gets home, you’d be yelled at as well. In psychology, this is called displacement. 

This is not to say, however, that you should immediately take off your clothes when you see your partner in a bad mood. Work your way into your partner’s heart first, and then seduce him or her. After that? Let your love-making take that stress away. 


A romantic relationship needs to be nurtured for it to work. Since sex allows for this nurturing, it becomes an integral part of any couple’s relationship. But don’t be too traditional and go straight to the sex. You can spice things up a little bit first so you can leave your partner wanting more. Apart from visiting sites you both like, sex toys can be an option. When it’s time to do it, you can also try different positions. Just relax, explore together, and reap the benefits to your relationship.
