Last week I was travelling across Iran, where I noticed a weird trend – a lot of women (and a few men) had bandaged noses.

An Iranian friend informed me they were all recovering from recent nose jobs. “They are proud to let everyone know that they've had a nose job!” he said. That's strange – is artificial beauty something to be proud of?

10-couple? One partner is shaped like a 1, the other like a 0. Does it matter in a sexual relationship?

We asked Carlos and Cecilia. He’s thin as a rail, her figure is, well... very full. Sure, they don’t fit the stereotype of a compatible couple. But the two lovers say size doesn’t affect their sexual chemistry. They told Love Matters the intimate secrets of their sex life.

This blog is a must-read for all chiseled-faced, six-packed hunks out there. It turns out your life is not as blessed as you thought.

Apparently girls are dumping good-looking men for being too attractive. It seems hot guys aren’t to be trusted. Phew. At last I’m one up on my better looking brethren. This is such incredibly good news that I couldn’t have even made it up.

So last Sunday I finally shaved off my beard and moustache.

Opinions have been divided. Wife thinks that I look much younger (I hope she means cuter) but best friend took quarter of an hour to get over his laughing fit. And I worry if the lack of facial hair brings too much attention to my oversized nose.

When guys are looking for a short-term partner, they just look at a girl’s body – more particularly, the ‘waist/hip area’.

They only start focusing on her face when they’re thinking of a long-term partner. Not exactly surprising. But there are probably evolutionary reasons. Guys check the body to look for fertility. They check the face to work out character – will she make a good partner?

“Is every girl’s vagina dark in colour or is it just mine? I'm really worried. And I’m not sure if my husband will like my vagina being so dark. What can I do?”

For women that share this lady’s concerns, there's a new vaginal fairness product on the market. Critics have branded it “the ultimate insult to a woman”.

“No matter where you are on the attractiveness scale, there’s always someone out there who finds you attractive,” says Danish researcher Gert Martin Hald.

He stumbled upon this finding in a study on how people respond when strangers chat them up. Hald told Love Matters about his surprising unpublished discoveries at the World Congress for Sexual Health.

“Hi there! Would you go to bed with me tonight?”

A guy who tries this chat-up line on a girl is heading for a big brush-off. Yet reverse the roles, and the guy will probably seize the opportunity (as well as the girl) with both hands. Sounds obvious? Danish researchers set up a ‘sexual invitations’ experiment to test the theory.

It’s in a man’s genes to think a woman’s interested even if she’s giving signs that she’s not, say US researchers.

Many men are built to get it wrong, according to Dr Carin Perilloux, who used speed-dating to explore the mating game. The more women a man thinks are into him, the more women he’ll chase after. This increases his chances of passing on his genes.

Men with deep, sexy voices have less sperm in their semen, an Australian study found.

Women find guys with deep voices more attractive than those with higher voices. So is a deep voice nature’s advert for top-quality sperm? It turns out the opposite is true. Deep-voiced men’s bodies put more energy into giving a good show than into making sperm.
