"Here's the breakdown - about 60% of women can't orgasm from intercourse alone. 20% can orgasm from intercourse occasionally, but need other stimulation, while a final 20% can almost always orgasm from intercourse. And of those women, 5-10% are capable of multiple orgasms. Those women actually don't like oral sex - it's too much for them. Too much stimulus."
