Women might learn to keep their previous sex lives private from their previous partners, since there is a good chance he might not approve.

A survey released Tuesday by men's website xyyz.ca in Toronto explained that while women are not very likely to share how many partners she had previously with her current lover, it's probably for the best - more than 40 percent of men believe that if she's had more than 10, then she's had too many.

Yet they don't hold the same standards for themselves and their own philandering around.

Nearly half of men will all too often answer the same question of how many sexual partners he had with a little reluctance before rounding the number away from the actual figure - up to 61 percent of men who report the number inaccurately round their answers up.

But that doesn't change their views on how many men their lovers should have tallied before them.

Women tend to ignore the question of partners when they are asked at a whopping 62 percent of survey takers.

About 42 percent of women think "there is no such thing as too many" partners and 31 percent think "it depends" on the circumstances.
