According to the Journal of Research in Personality, which was cited in the study, folks in romantic partnerships who process laughter and comedy in similar ways end up having a better time with one another.
"Laughter plays an important role in romantic relationships -- whether or not it's shared together or directed at the significant other. If partners handle laughter or being laughed at in a similar way, they tend to be quite content with their relationship. People who are afraid of being laughed at, on the other hand, are often less happy in their relationship. This also affects their partner and their sexuality, psychologists from Martin Luther University Halle-Wittenberg (MLU) concluded."
