The belief that alcohol can lead to sexual risk and/or sexual inadequate behaviors is nearly ubiquitous. But can we talk about causality? Several studies, with different methodology, have been developed during the last decades in an effort to understand the relationship between alcohol and sexual behaviors and function. From the knowledge that we already have, it is worth it to highlight alcohol consumption effects on cognitive appraisals, based on Response Conflict Model or Alcohol Myopia Model, as well as the expectancies effect. Future research is essential, specially to overcome the failures and limitations of the previous studies.
