This study aimed to describe the quality of the intimate relationship among parents six months after the birth of their first child. The Dyadic Adjustment Scale (DAS) has been modified and used on 820 responding first-time parents, of which 768 were couples. The results reveal that most parents were happy in their relationship, but both mothers and fathers were discontented with the dyadic sexuality. "Being too tired for sexual activity" was a problem, especially for the mothers, and the most common frequency of intercourse was once or twice per month. The result does not support the assumption that the couples compensate the lacking sexuality with sensuality. Good communication within the couple was associated with higher levels of several dimensions of the intimate relationship, especially dyadic consensus and satisfaction. Thus, one way to stabilize and strengthen a relationship when dyadic sexual activity is low would be to emphasize dyadic communication and sexual activity.
