If you feel like faking a headache when your partner wants sex, think again! Making love actually has many hidden health benefits -- migraine relief included!

Sex eases migraines

Almost 50 percent of women report post-nooky migraine relief, according to Randolph W. Evans, M.D., clinical professor of neurology at the Baylor College of Medicine in Houston. Evans believes that the release of morphine-like pain relief endorphins after sex aids to relieve or reduce migraine headaches.

Sex improves your immune system

According to a study by Wilkes University in Pennsylvania, people who have intercourse at least once a week show a 30 percent increase of the antibody immunoglobulin A, IgA, your body's first line of defense against colds and flus.

Sex reduces stress

A study by Biological Psychology found that people who have sex have lower blood pressure than those who abstain. It is believed that sexual activity creates a calming effect that lasts at least a week.

Sex cuts your endometriosis risk

Women who orgasm frequently are less likely to develop endometriosis, says Harvey Kliman, M.D., a researcher at the Yale University School of Medicine, who conducted the study to explore the effects of orgasm on endometriosis. Kliman believes this is due to uterine contractions which push out debris that might otherwise go back into the fallopian tubes.

Sex boosts your bladder control

Squeezing your pubococcygeus muscles -- the ones you use to stop the flow of urine -- during sex not only helps you achieve the big O, it also strengthens your bladder control.

Question: My boyfriend and I are looking for ways to explore using food in sex play. Any suggestions?

Think about the ways you can stimulate the five senses. Here's some food for thought:

Licking tasty treats like chocolate syrup and honey off each other's erogenous zones are a favorite among couples. But you can up the experience a notch by incorporating a little sensory deprivation: If you haven't tried already, you can take turns to blindfold each other while you relish every inch of your partner's body. The lack of sight, the feeling of not knowing when and where you're going to lick next can make the experience intensely erotic.

A reminder, though: It's best to keep sugar-based foods off your tender private parts. Sugar encourages the growth of yeast and bacteria, so use sweetened syrup and beverages only on other parts of the body.

If you're adventurous enough, some foods such as cucumbers can be used for insertion play. Make sure there are no rough surfaces, and always use lube and condom for protection. Keep oily foods away from condoms as oil can break down the latex.

Ice is another favorite. You can add the element of scent into your foreplay, simply by putting a drop of food essence (like strawberry essence) in water before freezing. Take the ice cube into your mouth, before you give each other oral pleasure, for simultaneous sensations of hot and cold.

The menu is really up to your imagination -- have fun experimenting!

If you're fishing for a potential date, here's a piece of advice for you: Don't do it when you're drunk.

The "beer goggles" phenomenon is real, say scientists from the University of Bristol in the UK, who conducted a research involving 84 heterosexual college students. The students were given either an alcoholic lime-flavored drink (enough to make some students tipsy) or a non-alcoholic version. After 15 minutes, they were shown pictures of people their own age, from both sexes.

The students who had consumed alcohol rated the faces as being more attractive than those who did not. In addition to increased perceptions of attractiveness, previous studies have also shown that alcohol lowers inhibitions, and drinkers are more likely to engage in risky sexual acts.

You probably know most of the sexual hotspots on you and your guy. But here are some lesser-known erogenous zones that pack pleasure potential, say sexperts.

The Small of Your Back

We all have a sexual hotspot located just below the coccyx (the vertebrae in the small of your back, right above your buttocks). This area contains sacral nerves, which when slowly massaged, heighten sensations around the groin.

Move to try: Lie on your stomach and have your partner wiggle his finger there slowly but firmly.

Your Ankles

In Chinese acupressure, the sunken spot between ankle and Achilles tendon is known as "the bigger stream". Stimulating "the bigger stream" releases feelings of pleasure throughout your body.

Move to try: Place two fingers on the area and firmly rub for 30 seconds.

Your Nose

Your sniffer is richly packed with nerve endings, and your nasal passages contain erectile tissue that increases sensitivity when aroused.

Move to try: Nibble on the tip of his nose. 

The Soles of Your Feet

Neurologically, the feet and sexual organ areas criss-cross the same neural pathways, making your soles of your feet a super-big erogenous zone.

Move to try: Press on a spot on the bottom of your man's foot, about one-third of the way down from the third toe. It's an acupressure point called "the Bubbling Spring" -- pressing and holding this spot for a few seconds can releases sexual energy.

With more and more people finding love online, this factoid can prove useful: Namely, your date's profile on online networking sites (such as Facebook) can reveal whether he's actually a narcissist.

Researchers from the University of Georgia gave personality questionnaires to nearly 130 Facebook users and analyzed the content of their online profiles.

What they found is that the number of Facebook friends and wall posts (messages left by the owner of the profile or friends) that a person has correlates with narcissism. Laura Buffardi, a doctoral student in psychology, said this is consistent with how narcissists behave in the real world, with numerous yet shallow relationships.

A self-obsessed Facebook user will boast thousands of friends and update their "status" non-stop. "Sometimes they'll have a famous (Ralph Waldo) Emerson quote, but they'll include quotes from themselves or something flattering someone else said about them," Buffardi said.

And guess what, narcissists are also more likely to choose glamorous, self-promoting pictures for their main profile photos, while others are more likely to use snapshots. So if you see him posting photoshopped, look-at-me pics of himself, he probably has a narcissistic streak.

Just the other day, I was hanging out with one of my girlfriends, Giselle. We were talking about nothing in particular, but one topic led to another and the subject on nudity came up. "Which guy wouldn't love the sight of his woman naked?" Giselle remarked rhetorically.

That may be true, but it got us wondering what's sexier than taking everything off. After asking the men, here's what I got: Keeping some bits covered up is often sexier than going totally naked. The implied nudity probably adds to a sense of mystery, and his imagination can do the rest and, ahem,  fill in the blanks.

Here are the sexiest outfits that drive men wild:

"The sight of my girlfriend walking around in nothing but her garter belt -- it makes me want to have my way with her right then and there." -- Max, 27

"My wife in her satin slip. Brazilian waxed." -- Lo, 33

"A see-through mesh bra is an instant turn-on." -- Jeremy, 25

"When a woman wears nothing but a pair of killer heels that says she wants to take control." -- AJ, 29

"A low-cut dress." -- Vincent, 39

"I love it when my wife wears my white shirt, braless." -- Bryan, 32

"There was once my girlfriend went out with me wearing a very tight skirt. Then she whispered in my ear that she wasn't wearing any underwear." -- Gary, 26

How can you tell whether a guy really likes you or if he's just looking for a casual hook-up? According to anthropologist David Givens, Ph.D., who specializes in nonverbal communication, when a man is serious about the relationship, he demonstrates loving acts that show he cares. So, you know you're more than just a fling when he:

• Holds your hand
• Grooms your clothing, or plays with your hair 
• Doesn't lose interest after the third date if sex hasn't occurred 
• Calls you the day after making love 
• Doesn't let his eyes wander when he's with you 
• Attends to your needs (but not excessively so)
• Touches your arm, shoulder, or back -- but not at every opportunity 
• Doesn't make a pass on the first date

One in five of all married couples spy on each other's emails and text messages to ensure they are not cheating, say Oxford University researchers.

And 13 percent of those surveyed have confessed to checking up on the browser's history to find out what their partner had been surfing.

While many couples said the internet was useful for maintaining a relationship, they also admitted it could be a threat by opening up the opportunity for "online infidelity".

Unsurprisingly, 97 percent of respondents would be unhappy if their partner fell in love with someone else via the internet and 92 percent would not be pleased if their other half disclosed intimate details of their relationship to others.

When it comes to visiting adult sites, however, men and women have slightly different views on the matter, with men more likely to accept such behavior in their partner than women.

Yes, you read right. Men have what many sexperts describe as the male equivalent of a woman's G-spot, and few males are even aware of this pleasure zone in them. It's called the prostate, a walnut-sized gland surrounding the urethra which creates the fluid secretions in semen. And when stimulated right, it is capable of giving your man explosive Os.

Hot move to try: Wrap your hand around his erect shaft and then move it toward his body instead of the usual up-and-down motion. Manually stimulating his penis this way causes its erectile tissue to press against the prostate (which lies just behind). You're basically stimulating his two hottest spots at the same time!

When you're in a long-term relationship and things have become "routine", it's easy to start taking each other for granted. It's not that you don't love your guy as much, it's just you don't show it as often as before. Keep your love connection strong with these sweet acts that say "I love you".

Do small favors for each other, such as recharging each other's cell phone, topping up coffee for your partner, etc.

Leave a note on under his pillow that says "You're the best hubby -- ever! Thanks for always being there for me."

Run him a hot bath (complete with a glass of wine by the tub) when you know he's coming back home from work.

Tell him one thing you appreciate about him everyday, and vice versa. You'll both get an ego boost.
