Sex research has shown that about 95 percent of men nearly always have orgasm from intercourse while only about 25 percent to 30 percent of women do. Another 30-some-odd percent of women never have orgasm from intercourse, and a middle 30 percent to 40 percent report having them sometimes.

Maybe the difference has more to do with male ineptitude? Wham bam thank you ma’am ... rather than having the skill or desire to bring the act to mutual satisfaction. Just saying.
