get a book on tantric sex; opens up a whole new world for you boys. also, those claiming their women cum instantly, my money says she's lying to protect your ego. statistically speaking, a woman who cums on penatration is a freak of nature (plenty of research to support this, read a few studies. these studies also support the fact that MOST women fake it - OFTEN). if it's true, she is unbelievably rare and lucky. :-)
