Objectives:
The aim of the present research was verification of the hypothesis for the influence of negative sexual experiences in sexual development on the quality of partner relationships in the adult life. Special attention was given to the influence exercised by the level of erotization in the environment of the family of origin and to the experience of child sexual abuse. The quality of partner relationships was recognized using Jurg Willi’s concept through the analysis of intensity of dysfunctions (collusions) in those relationships.

Methods:
The study was conducted on a population of 170 adults in partnerships. The surveyed group filled in the Questionnaire on Models of Sexual Upbringing in Families, the Couples Collusion Questionnaire and the Questionnaire on Sexual Abuse of Children.

Results:
Positive interrelation has been confirmed between the level of erotization in the family of origin and the oral, anal and oedipal partner collusion in the procreative relationships of individuals. Such link has not been confirmed for narcissistic collusion. The interrelation between the sexually abusive experiences and the partner collusion has only been confirmed in masculine group within the oral collusion and the anal collusion.

Conclusions:
The findings largely support the assumption that there is a connection between the character of sexual experiences in childhood and functioning in adult partnership.
