Annie, 25, a physio, and Francis, 30, a policeman, have lived together for 2 years.
Francis: I don't have a problem with different sex acts and I love giving her cunnilingus - we both enjoy it!
Annie: It took me a while before I first gave him a blowjob because I think it's very intimate and I'd never had a serious relationship before, so it was quite a big thing for me.
Francis: We go to sex-shops together for a laugh and have a look at new things. I've only ever has a serious conversation about sex once with a friend. We always joke about it at work, but more like you do with your mates when you're growing up.
Annie: I don't have a problem with sex and I love to do it, but I find it difficult to talk about with my close friends.
