Has anyone heard of stopping and restarting finasteride, inducing persistent sides?

I have been on finasteride for about 4 years now. Over the course of time that I was on it, I did notice reduced libido and less erections but it wasn't too bad. About a year ago, so my third year on the drug, I wanted to take a month off to see if I felt any different. Within 2 weeks I felt a massive spike in my libido, as well as more erections. However I was scared of losing my hair, so I went back on Fin. My logic was at worst I could quit again down the road and stay on until a better treatment comes along.

Fastforward to this summer. Again I decide to take a break. Paranoia got the best of me and I wanted to know if I could still return to normal function after quitting. I am now one month out and absolutely nothing has changed. Low libido and the only time I feel aroused is if I watch something stimulating. I am never compelled to masturbate, but rather I masturbate to see if I can get it up. I went one week with not masturbating and felt even less drive.

Is it possible that by stopping and starting again, I did something that will have a lasting impact on my physiology? It will suck if I am like this permanently. I have nobody to be mad at if that is the case though. I rolled those dice and if it means I have to wait until the next one to be a sexual being, I gotta live with it.

Any advice? Thoughts? Or anecdotal experiences similar to mine?
