Use Hindsight. 
So was 2011 a bumper year for your orgasms, or just kind of flat? Either way, you need to answer this question: Why?
Using every year as a chance to improve your own knowledge of your sex drive, desires and changing tastes is a fun way to round off December. It's also the best kind of hindsight. Is this year the year you had to let go of your ambition to like anal? The year you discovered new nerves in your G-spot? The year you kicked a partner out of bed for rudeness? 
Look back, remember, cringe - and make sure you learn the lessons. If you're going to have better sex in 2012, you'd better pay attention to 2011. 

Try Something Out Of Your Comfort Zone 
It could all end horribly. It could be embarrassing. It could be silly. So what? Make 2012 the year to really push yourself in the bedroom. 
If it's kink you've never tried, invest in a few new fun accessories and start - slowly - to try them out. If you've never tried a certain position - on the edge of the bed, standing up, legs-over-the-shoulder - look it up and try it now. If you've only had really hardcore kinky sex for a while, why not change pace a bit here too? 
Sex is about variety, but that doesn't mean missionary is boring or stale - it's standard because it often is one of the positions that really works. So keep searching for quality, not just new thrills. 

Update Your Toy Collection 
A woman without sex toys is a woman who's missing out, generally speaking. (Hey, you might not like them - and that's cool.) However, if you've got the same old tired vibe and eggs you had years ago, now might be time for a change-over. New year, new equipment! 
Sex toys are one of the biggest areas of innovation at the moment. JimmyJane and Lelo are putting out toys of such quality and increasing efficiency that they should be working for NASA. Look for things which target the spots you know you like - G-spot, clit, deep penetration - and maybe throw in something a little different, like a finger vibe or a corset. Always aim to improve your experience rather than make it the same old thing. Toys are a great way to achieve that quickly and easily - and they make for pretty good Christmas presents from partners, if you're at the dropping-hints stage... 
A note: don't go for solid-gold versions unless you are a Russian oligarch. Make sure to enter Rescu's We Vibe 3 competition. You could score a new toy for the new year without paying a cent!

Move Out of the Bedroom
This is one of those tired cliches of sex-reporting: a new location can add new spice. It's worth writing down. Spontaneity and opportunism go hand-in-hand with quickies in unexpected locations - the kitchen, the shower, a cloakroom at a party. It's the forbidden factor that's essential, here. It can be difficult if you have kids or roommates, but plan carefully. Maybe you'll both enjoy it.
A hint, though - don't go anywhere deliberately looking to get caught, because the thrill quickly wears off with an Indecent Exposure charge and a court appearance.

Eliminate Moves You Hate
It's rare to meet a woman who really, truly enjoys reverse cowgirl, because the view is so boring. I'm sure they're out there, but if the position's not doing it for you, toss it. Sex is an act of constant evolution and keeping in tune with your body. If you've given a position the best chance you can and it's not giving you any pleasure, consider scratching it from your list. This isn't just your decision, though.
If your partner adores it- like, SERIOUSLY adores - there's going to need to be negotiation, and it's not fair for you to simply pull an item from the repertoire without consultation and explaining. This may make things pre-meditated and odd, but at least there won't be a situation in the bedroom which ends up with one partner begging and the other refusing.
If you're single, do whatever you like. Not going to give another blowjob to a man who hasn't trimmed? Banishing nipple clamps forever? Good on you.

However, do remember that feelings and bodies change, and that next year you may want it all over again..
