Countless research and self-help books claim that having more sex will lead to increased happiness, based on the common finding that those having more sex are also happier. However, there are many reasons why one might observe this positive relationship between sex and happiness. Being happy in the first place, for example, might lead someone to have more sex (what researchers call 'reverse causality'), or being healthy might result in being both happier and having more sex.

In the first study to examine the causal connection between sexual frequency and happiness, Carnegie Mellon University researchers experimentally assigned some couples to have more sex than others, and observed both group's happiness over a three month period. In a paper published in the Journal of Economic Behavior & Organization, they report that simply having more sex did not make couples happier, in part because the increased frequency led to a decline in wanting for and enjoyment of sex.

The couples instructed to increase sexual frequency did have more sex. However, it did not lead to increased, but instead to a small decrease, in happiness. Looking further, the researchers found that couples instructed to have more sex reported lower sexual desire and a decrease in sexual enjoyment. It wasn't that actually having more sex led to decreased wanting and liking for sex. Instead, it seemed to be just the fact that they were asked to do it, rather than initiating on their own.

Despite the study's results, Loewenstein continues to believe that most couples have too little sex for their own good, and thinks that increasing sexual frequency in the right ways can be beneficial.

One of the study's designers, Tamar Krishnamurti, suggested that the study's findings may actually help couples to improve their sex lives and their happiness.

"The desire to have sex decreases much more quickly than the enjoyment of sex once it's been initiated. Instead of focusing on increasing sexual frequency to the levels they experienced at the beginning of a relationship, couples may want to work on creating an environment that sparks their desire and makes the sex that they do have even more fun," said Krishnamurti, a research scientist in CMU's Department of Engineering and Public Policy.
