I'm a few months from 21. I've speculated that I might have Prostatis or Cystitis that made me lose my sex drive, but after some research, I think it's because of high serotonin levels.
High levels of serotonin (found in Prozac)hinders sex drive and reduces emotions/ feeling in general. Thinking about it, I used to be sort of nervous/anxious all the time, and it suddenly stopped. I haven't been taking any prozac or similar medication, rather I have matured mentally that's why I don't feel anxiety or any much emotion at all. I think my body raised serotonin levels naturally for some reason.
Thus, I have low libido. What should I do? ****, I miss being horny all the time.
