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. 
Ni muhimu kufahamu kuwa, katika muktadha wa utafiti wa Sagami, watu ambao waliokuwa kwenye mahusiano ya kimapenzi na waliosema kuwa walikuwa sehemu ya "ndoa isiyoshiriki tendo la ndoa" waliweka bayana kama walikuwa wakishiriki tendo la ndoa na wenza wao au hawakuwa wakishiriki nao.
