Bananas, when ripe, can have different sizes and colours, including yellow, purple and red. Banana fruits are rich in nutrients that are important for the production of sex hormones. Because of its obvious phallic form, banana easily represents sexuality. However, in practical terms, bananas have a lot of vitamin B and potassium, which are important in the production of sex hormones. They are also rich in chelated minerals that help the body to absorb essential nutrients and thus strengthen male libido. The sugar content in bananas gives energy and helps to stay longer in bed.
