The main objective of this study was to determine the predictive capacity of different variables, organized based on Ecological theory (i.e., personal, interpersonal, social, and ideological), in the intensity of the subjective orgasm experience within the context of heterosexual relationships. The sample was composed of 1,300 adults (547 men, 753 women). The proposed model for men showed that more intense subjective orgasm experience was predicted by age, sexual sensations seeking, sexual satisfaction, and partner-focused sexual desire. The model for women showed that more intense subjective orgasm experience was predicted by age, erotophilia, sexual sensation seeking, partner-focused sexual desire, and sexual satisfaction.
