Perhaps you've heard that size matters, women are naturally more bisexual than men, or that tantric sex means everlasting orgasms. None of these things is entirely true. Sex has been around forever, but we're just starting to understand it. Today we're debunking 10 of the most common sex myths to set the record straight.

Dear Lovehacker, my wife and partner of 15 years has left me for a guy she met online in the MSN days. But she wants me to stay living in the house to fulfill her needs. She has been talking to him on and off for the entirety of our relationship and has secretly flown out to see him when I've been away.

I want to stay for my kids and give them the closest thing to a normal life as possible. And I still love her, but I guess she doesn't feel the same. Should I leave?

I'm a 25 year old woman. I'm not "Victoria's Secret model hot" but I'm also aware I'm good looking. I'm told I'm "unique" (eye roll), and I have diverse interests so I usually don't have any problems getting along with people unless I find them absolutely boring. But anyway...

I have a weird problem: People only wanting to get into a relationship with me. It's absolutely not what I'm looking for. Although I'm incredibly sexual, I don't have "romantic feelings".

If someone were to tell you there are various types of orgasms that women can have, what would your reaction be? Surely, an orgasm is an orgasm and there’s only a couple of ways to reach that big ‘O’? Think again! It turns out women can achieve 12 different types of orgasms. Yes, 12! Read on to find out more about the ‘Dirty Dozen’ and how you can have them (or give them).

Nobody enjoys being with someone who is always passive aggressive. If you're not sure what that looks like, here's an excellent, and funny, demonstration.

It’s perfectly normal for couples to argue. But sometimes those arguments aren’t particularly productive and spiral into vent sessions instead of useful discussion, and sometimes they can even be destructive. This is avoidable.

This week, Australia's biggest gaming convention PAX returns! Gamers from around the world will be descending upon Melbourne for some fun, fandom and, if I have anything to do with it, flirting! Not sure where to start on your geeky romance journey? Here are a few tips.

So, you’ve been rejected. Maybe someone turned you down, maybe you got dumped, maybe your partner asked for “space”. How do you win them back? Don’t.

Sometimes at the end of a relationship, we’re so sure we want nothing to do with the other person that we’re happy to scorch the earth with the break up conversation. But it’s probably better to do it with some compassion and empathy.

Dating, of course, is a delicate dance with many unknown factors at any given moment.

Just because you've waited until the very last minute doesn't mean you don't care. Well, it kind of does - but your better half doesn't need to know that. Here are some quick-fix Valentine's Day gifts that should help to keep you out of the dog house.

Dear Lovehacker, I moved cities late last year and my old boss is going to be in town for a visit soon. He suggested that we catch up but my only availability was during the evening. I didn't even think that it could be a problem until after we arranged to have dinner. He has a wife and I'm not sure if I should be worried about what she would think, especially because I'm single. Am I just being paranoid or is there something a bit off about having dinner alone with a married man? Thanks, B.

If you’re someone who is already planning a surprise public proposal, you might be in too deep to know that it probably isn’t a great idea. However, if you’re willing to hit pause, maybe go through this checklist before arranging the flash mob dance.

Controversy over vaginal versus clitoral orgasm is nothing new; it's a debate that has consumed sexologists and psychoanalysts for the last 100 years. Modern research has just added fresh fuel to the controversy.

To paraphrase award-winning author Garth Marenghi, there are only three hetero sex positions worth doing: doggie, woman on top and "normal". But which one is best?

Medial doctor and sex therapist Zvi Zuckerman (aka the "Sex Doctor") recently explained the scientific, romantic and physical benefits of each position, along with their potential drawbacks. So if you're feeling frisky tonight, here's what to look forward to (and what to look out for!)

A few months ago, I shoved a freaky contraption up my vagina to strengthen my pelvic floor muscles in a quest for earth-shattering orgasms (for science, of course).

Lying in bed, staring at my ceiling while concentrating on squeezing my pelvic muscles with a giant piece of plastic up my hoo-ha isn't exactly fun so I quickly gave up on it. But Elvie, a discreet toy that gamifies vaginal exercises, does look like a better option.

The next time you're having a "quickie", you might want to keep a watchful eye on the clock. According to the latest scientific research, "acquired premature ejaculation" includes any encounter that lasts less than three minutes.

Er, does that include taking your clothes off? Asking for a friend...

Dear Lovehacker, So I'll just be completely honest and upfront with you from the jump: I'm not exactly what you'd call a "smart" man. Not like special needs or anything, just, a little slow. Despite putting in a lot of effort during high school, certain topics just eluded my grasp, mostly maths and science courses.

That being said, I'm actually doing really well right now, despite being kinda dumb. I have a job that pays very well, I live in an apartment that's not a total crap-sack for the first time since I was 18 and living at home, and I have a very seriously cool partner. Her name is A, and she is the smartest, and most fiercely independent woman I've ever met, which for me is "The Dream" you know. However, I recently met A's friends which is where the problems started.

Spanking is great. It builds anticipation, provides scintillating sensation and can amp up role play. If you’re thinking about trying a paddle, you probably know all this already and have experimented with palm spanks. (If you haven’t, you should do that first.)

If you have, indeed, sampled the delights of hand-to-butt spanks and your sub enjoys it but wants more, then a paddle is a must-have for your toy box.
