my wife has wonderful, very intense orgasms just about every time we have sex. it usually takes anywhere from 5 minutes to a half hour. afterwards, she is very sensitive though... not so much that we cannot continue, but enough that it is uncomfortable to stimulate her clitoris directly. we can manage multiple orgasms only if we have sex for a very long time after her first climax, like >1hr... and she typically is too tired to invest that much time... any tips for achieving a rapid 2nd/3rd orgasm? thanks!
