20 year old male here suffering hair loss from the age of 15 I was taking finasteride for just 4 days and I'm really anxious about my sexual functionality. And I don't know if it's just my anxiety or the drug really causes some problems with my Penis. I read the horror stories before getting onto the pill. Maybe that causes that. I didn't even pop the fourth pill but I feel kinda my penis is not like it used to be. I can have an erection. Even I had morning woods but as soon as I think about something or even if not my erection goes away. I didn't even had watery semen yet but my Penis feels strange Is it just anxiety or real side effects?
