The aim of this study was to test the hypothesis that those with insecure attachments (characterised by anxiety, avoidance or both; Hazan & Shaver, 1994), would engage in less effective communication on sexual matters, which would in turn predict lower sexual satisfaction. A sample of 125 participants aged between 18 and 65 completed an online questionnaire asking about their sexual and intimate relationships, and their attachment patterns. As expected, avoidant individuals reported poorer sexual communication, which contributed to their sexual dissatisfaction. Contrary to expectations, anxiety did not have this effect. Interestingly, those anxious individuals in a relationship of 9 months or longer engaged in poorer sexual communication, which negatively impacted their sexual satisfaction. It was suggested that the ‘honeymoon period’ may be responsible for this finding. Alternatively, and as suggested by Davis et al. (2006), other variables, such as sexual anxiety and using sex as a barometer of relationship status, may account for this effect and warrant further exploration.
