When it comes to sex, athletes are no exception. However, can they have sex before a big competition? This is undoubtedly a common concern among athletes, coaches, and team doctors from all countries. According to the German publication "Daily News," a survey conducted by two Israeli scientists has proven that female athletes having sex before a competition helps improve their performance. The two Israeli sexual medicine experts from Jerusalem conducted experiments on 28 female athletes. The "Daily News" quoted these two scientists as saying: "Libido enhances their confidence, giving them strength and courage." If sex helps improve female athletes' performance, then what about male athletes? In previous years, it was commonly believed that pre-competition sex would make male athletes tired, which was not conducive to the competition. But in recent years, this view has been seriously challenged.
