If you have a good memory, you might recall a certain study in 2004 that said increasing the amount of intercourse you have from once a month to once a week would give you the same amount of happiness as receiving an extra $50,000 in the bank!

But beware: more sex doesn’t necessarily mean more happiness, according to a report published this year. The researchers of the latest study found that couples who had more sex because they were asked to for the study reported that the sex was not enjoyable and did not make them happier.

Therefore, sex will only lead to happiness when the couple is having it for a meaningful reason, the researchers conclude. So, whether it’s once a week or once a month, the frequency is less important than the purpose behind the act.
