A survey of Japanese students found that 62% of Japanese university coeds are not virgins, a rise of 10 percentage points since the last survey six years ago. This compares with only 11% of female university students in 1974 who admitted to having sex.
The survey also found that 30% of senior high school girls (as opposed to 27% of the boys) and 3% of middle school students (both boys and girls) are sexually experienced.
Is there any information on how that compares to American or Canadian statistics? It would be interested to compare the both of them..
