So far, 52% of respondents report orgasm from intercourse alone either always or usually. I realize ours is not a scientific sample, but I am still surprised. I expected the numbers in these categories to be much lower. An expert at the Foundation for Intimacy suggests that only about 30% of woman orgasm during intercourse (

An article on the BBC website puts the number of women who orgasm during intercourse much lower at 25% (
