How can I have more than one orgasm?

It can be done! There is a great book called eso, extended sexual orgasm by dr. Alan and donna brauer. It talks about how a man can help a woman have multiple orgasms. They even have a work book. Read that first. Having a patient skilled partner helps, have him read the book too. It would very difficult to do what that book says by yourself, you really need a good partner to make it work.
YOU CAN IF YOU TRY. Most women can have more than one orgasm with the right teqnique and with the right partner and you can can experiment different positions, more foreplay and learn from the books suggested, but do not get obsessed with it as it can ruin a relationship and make you unhappy.If you still dont have more than one, be happy that at least you can have one.
