Post your strange body function/malfunction: no need in sleep or take a shit once a week

My sexual drive is 0 for 5-6 months. I can watch porn and don't even get hard,(can if i start to stimulate dick but ejaculation wont be joyful) no interest in girls and so on. After 6 months i get normal libido, i can cum 2 times a day no problem. Will get diamond from a thought and if i open porn site i will almost shake from arousal. This will continue for 2-3 weeks than it drops to 0 for 5-6 months again.
