It's important to note that, in the context of the Sagami survey, people in couples who reported being part of a "sexless marriage" were simply reporting on whether or not they were having sex with their partners.
В контексте исследования Sagami следует отметить, что женатые люди, говоря о «платоническом браке» (и отсутствии секса) имеют в виду только официальную партнершу.
