How serious of a side effect is the loss of morning erections on Finasteride?

I was on finasteride for almost 5 months but it seemed to make my hairloss worse so I quit. After stopping, I realized that I had not been experiencing morning erections or nocturnal emissions while I was on fin. These returned a few days after quitting. I was thinking about giving fin another shot so I wanted to know if these side effects were a sign that I could have a bad reaction and experience worse side effects if I try again. I did not notice any sexual side effects other than these.
