The friend of mine is going to research motivational and behavioral aspects of sexual functioning in couples with different attachment orientations

She needs questionnaires or semi-structured diaries covering the following points:

- subjective motivation for engaging in sexual activities

- a range of behavioral measures (e.g. frequency of intercourses, sexual arousal, initiation and enjoyment of sexual activities, erotic foreplay, negotiating about sex, orgasmic responsivity, masturbation and pornography use etc.)

Thank you for advice.
