You should read the product insert and Google it a bit.

Finasteride is a 5-alpha-reductase-inhibitor. It stops Testosterone from being converted to DHT.

DHT causes male pattern hair loss that is why you get your hair back.

DHT also is a very important hormone for sexual wellbeing. That is why you are getting a loss of libido and ED. These side effects happen in about 7% of people who take Finasteride and they CAN BE PERMANENT.

Another common side effect of Finsteride is male boobs aka gynaecomastia. Or sometimes men just get a tender breast bud under their nipple.

I have nothing against Finasteride. The fact is it is a really good and effective treatment for male pattern balding. Many patients take it with no side effects.

I think you just need to be aware of the potential risks and make an informed decision about your treatment.
