Erectile Dysfunction with finasteride

I took fin for 11 days, stopped because i was afraid of the sides. Then four days later i tried to have sex with my gf, but i couldn’t get it up at all. After some days it went back to normal.  But some weeks later i tried to have sex again, and my penis didn’t get up. I had this on my mind before the act, so that may have been the case. We had sex later that day, and i felt better, and the next day we had sex three times.

I maybe suffer with PFS? Going to an neurologist soon. I have also tried a quarter pill of viagra, but that doesn’t help much. Is this just me overthinking?  

Yes, you are focusing too much on your penis and performance. That, by itself, can give a man ED.
