Every girl should have a second-best friend. The sort of friend that can almost instantly make you feel good, de-stress you, and help you ignore all those niggling pieces of life that just won’t go away. The best part about it is that these friends aren't difficult to find at all - all you need to do is hop online and you can get them delivered in discreet packaging from an obscurely named company, right to your letterbox. Every girl's second best friend should be a vibrator - here are the top 5 reasons why!

1. Because sometimes you won’t have a partner Sex is a natural part of life - but if you don't have any handy humans to take out your sexual urges on, and would rather skip the baggage and risks associated with one-night stands, a vibrator is an excellent alternative. You can use it for quickies or slowies - while watching porn or just quietly in bed at night before you go to sleep. There is a stack of research that shows that orgasms help maintain your mental, emotional and physical wellbeing, and there's no need to miss out on those benefits because you aren’t in a relationship.

2. Because when you do have a partner, you want to add a bit of pizzazz
Sometimes making a girl come is hard work for guys … girls actually have it sort of easy in that respect! A vibrator can help you have longer and stronger orgasms, and keep going back for second and third helpings, when your poor dear is worn out. Vibrators can also be used anally, or extra-anally (around the outside of his bottom, pressing against the prostate) on guys with surprisingly explosive results!

3. Because vibrators help incorporate your whole body into the pleasure experience
Every little extra piece of stimulation you can get, either while having sex or masturbating, makes you feel that much more AWESOME! Your boyfriend/girlfriend only has one mouth - but you can use a vibrator on the other nipple for extra pleasure. It's a bit tricky to have him stimulating your clitoris while thrusting - vibrator to the rescue.

4. Because vibrators are instant stress relief
If you can just relax enough to get your vibrator out from the top of the closet, you'll find that using it provides an instant stress relief. In fact, in many organisms (all the way down to algae), sex is actually a response to stressful events in life. Your heart health, cortisol levels, and endorphin levels are all affected positively by having an orgasm. You also release oxytocin and DHEA (the antidote to adrenaline) during orgasm.

5. Because it's easier to buy a new vibrator than get a new boyfriend
And besides, who would want to change boyfriends like they do vibrators?! What we mean by this is that it is a lot easier to expand your sexual repertoire with new sex toys than a new sex partner. There are a hundred different types of things that vibrate and wiggle to make you feel good and relieve stress in different ways.

Vibrators are possibly one of the inventions that have done the most to put women on an equal footing with men … now we can bring ourselves to orgasm with the same ease that guys experience. Hurrah! They are becoming so much more accepted … and when even scientists are telling us they are good for our bodies, who are we to argue?
