Marie, 29, and Paul, 37, have been married for 4 years. Marie is a waitress and Paul a taxi driver.
Marie: Anal is a very personal thing and I only do it if I'm in a serious relationship. Still, we shouldn't think about it as something that only happens in porn films.
Paul: Marie wasn't up for it at all at the start of our relationship, but we talked about it, took our time and gradually she accepted it could be good. Obviously it's a real pleasure for guys, so you both need to be comfortable with it.
Marie: I mainly do it for him, but at the beginning I really wasn't interested - I thought it was all about being the dominated woman and I hated that. Thankfully, Paul didn't take offence and gradually we grew into it. Still, if I didn't do it I'm sure he'd miss it.
Paul: It has to be good for both of you. It's not easy to talk about it openly. Anal is definitely the most taboo subject in sex.
