According to a study carried out by sociological expert Daniel L. Carlson of Georgia State University (USA) and students Sarah Hanson and Andrea Fitzroy , heterosexual couples who share duties related to childcare They have a better quality sex life and a better relationship than those who do not . The study has been presented at the Annual Meeting of the American Sociological Association in Chicago (USA).
The researchers had the participation of 487 heterosexual couples in the 2006 MARS survey on Relationships and Marital Status. All of them were divided into three groups: the first, in which women carried out at least 60% or 100% of tasks related to the care of children; the second, in which men were responsible for at least 60% or all of the care of the children; and finally, a group in which both men and women shared the care of children equally ( supervision, surveillance, physical / emotional care and interactive care ).
At the same time, a test was carried out to examine the quality of the couple’s relationship, taking into account the quality of sexual life and also its frequency. The results revealed that when women took care of practically all the duties towards the children, the sexual life was of lower quality and less frequent than the group in which the couples shared this work. That is, the couples with the greatest sexual satisfaction were those who distributed the attention to the little ones in the house.
“One of the most important findings is that the only child care arrangement that appears as very problematic for the quality of the relationship and the sexual life of the couple is when the woman does most or all of the childcare “, Carlson explains.
Another of the conclusions of the study was that when the parents took care of most of these responsibilities, the quality and frequency of sexual relations was maintained positively for women , who claimed to be very satisfied -the most, of all the work – but not for men , whose results were the lowest in terms of satisfaction with their sex life.
