Fidel Castro has slept with over 35,000 women.
Journalist Ian Helperin learned this from a former employee of the Castro regime, when working on a documentary about the famous dictator. Over the course of 4 decades that averages to at least 2 women every day. This would be even higher than the legendary number of women that Wilt Chamberlain claimed to have bedded (20,000).
