Quaestor's main brief was to focus on Mates' new Intensify range, including Intensify Stimulating Gel and Intensify Vibrating Condom Ring.
As part of the study, Quaestor conducted bedside cupboard audits of items used in couple's sex lives.
According to Quaestor director Caroline Bond, the in-home methodology was in some ways easier to manage than the subsequent focus groups.
She said: "The biggest problem was not so much getting people talking about sex - as the traditional 'no sex please, we're British' view might have suggested - but rather that sex is such a different experience for different individuals.
"This was really highlighted in our group discussions for Mates. It was very challenging to moderate sessions where there was no consensus because experiences and attitudes were so varied."
According to the research, consumer attitudes to sex were increasingly linked to the current trend towards indulgence, pampering and a healthy lifestyle.
Rachel Hemmings, brand manager at Mates UK, said: "Quaestor's findings have helped us further develop the positioning and marketing communications for our Intensify range. They provided a wide range of valuable consumer insights on everything from the wording on the packaging to a much wider impression of couples' attitudes to sex and intimacy."
