DEAR DEIDRE: I’D rather do the dishes than have sex with my boyfriend – it’s such a chore.That’s why I’m having an affair with my married boss Sex is so boring at home so I ham having an affair I’m 25 and my boyfriend is 26. We’ve been seeing each other for four years.We moved in together two years ago. Since then our sex life has gone stale.We still have sex but it’s just so mind-numbingly dull.We do the same positions, on the same bed, at the same time every Saturday.In spite of this, I still love him. I think that’s why I feel so guilty for having an affair with my boss.But I can’t help myself as it’s the best sex of my life.It’s so exciting having sex on the desks once everyone leaves the office. It’s been going on for three months and I don’t know how to stop.DEIDRE SAYS: You need to understand that while your boss is giving you the thrill of the forbidden, that is where his commitment will end. Your boyfriend is the man you say you love, so stop the affair before you lose everything.It is all too easy for sex to become routine and humdrum in a long-term relationship.Take the initiative and have sex in different rooms, positions or even at different times.My support pack, 50 Ways To Add Fun To Sex, explains how to up the thrill without putting your relationship at risk
