Can all Women have multiple orgasms?
Some Women can and some women can't, or rather they think they can't! It can be difficult but not impossible. Let me preface this by saying there is no right or wrong way, you can take your time in between orgasms, there is no rule that says right after the first orgasm you have to jump straight into the second one. Sometimes its nice to just ride that wave.
My first suggestion is get yourself an Air Pulsation Toy! Seriously if you've never tried one then you need to immediately, this is not a drill. There are a lot of different options when it comes to choosing an Air Pulsation Toy, you can refer to my previous Blog to help narrow it down. So the reason I highly recommend Air Pulsation Toys for Multiple Orgasms is because they do not come into direct contact with the clitoris unlike a vibrator. When using a vibrator, especially one with intense vibration you can actually overly stimulate the clitoris so it becomes uncomfortable/painful to be stimulated or have an orgasm because the clitoris has become too sensitive at this point. The Air Pulsation toys work with Pulsation waves so that it sucks on the clitoris and feels more like oral sex and does not desensitize the clit, which makes it a lot easier to have multiple orgasms. 
Try mixing it up:
Try having different types of orgasms instead of focussing all your attention on one spot. Because the clitoris has around 8,000 nerve endings its obviously most peoples favorite spot. Try starting with a clitoral orgasm, then maybe move onto a G-spot orgasm, pay attention to other erogenous zones as well. Don't forget the Nipples, the neck, the earlobes and the lips. If you are a woman who can have an internal orgasm then try penetration after your clitoral orgasm, making the vaginal muscles a lot more relaxed which is perfect to then try a G-spot orgasm! You can also try using a clitoral stimulation oil. If you have never tried one before I recommend using the Sensuva On Original. Clitoral stimulation oils are made of either one out of three proprietary ingredients, either cinnamon which gives you a warming sensation or menthol or peppermint which gives a cooling sensation. I recommend the warming one for beginners because it is not as intense as the cooling ones, if you have used clitoral stimulation oils before then mix it up and try a cooling/tingling one, they're a little more intense but seriously bring a lot of sensation to the clitoris. We also carry edible ones now so that if you apply the oil and your partner decides to perform oral on you they are not tasting a mouthful of oregano! 
Using multiple toys at once:
I know that sentence can seem a little daunting but it is possible and fun! If you enjoy nipple play I suggest trying nipple clamps. You can venture into self penetration with a dildo. Most dildo's have suction cups at the base which are perfect for attaching to any flat surface like a shower wall or a non fabric chair and penetrate at your own speed and rhythm, while using the dildo you can also use a vibrating clitoral toy or an air pulsation toy on the clitoris so you are stimulating multiple erogenous zones all at one time!
Exploring Sexually, solo or with a partner is fun, try not to let the aspect of trying something new or not being 100% sure how to go about it discourage you, mix it up a little bit and chances are you'll be blown away, LITERALLY!!
Conclusion
The key to better and bigger orgasms is to figure out what to do when you are close to orgasm. Learn what pushes you over the top. When you learn that. It should be easier to have multiple orgasms. Whether that is with a toy, your hands or with the help of a friend is always a good idea.
