Why does my sex drive occasionally spike? I don’t really change my diet or living style, yet my drive goes up and down seemingly at random. There are times where sex won’t cross my mind for days. Then, out of nowhere, I can’t get it off my mind no matter how much I fap. This also usually lasts days. Is this normal or is something causing it? I’m 23 btw. Also, I know boredom isn’t the problem.
