Methods: Participants were 523 Spanish and 595 Portuguese heterosexual young adults who completed a background questionnaire, the ASEX, and measures of sexual sensation seeking, excitation, and inhibition. Results: The ASEX showed good reliability and validity. Participants reported good sexual function. The most prevalent difficulties in men were related to desire and orgasm, and to orgasm and satisfaction in women. Conclusions: This is a psychometrically sound instrument to assess sexual functioning in Spanish and Portuguese young adults.2017http://zaguan.unizar.es/record/8431110.1080/19317611.2016.1259706http://zaguan.unizar.es/record/84311oai:zaguan.unizar.es:84311INTERNATIONAL JOURNAL OF SEXUAL HEALTH 29, 2 (2017), 155-167All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
