Finasteride and sexual side effects

So I’ve been on fin for about a week and a half now. For the first week I noticed that the only side effect I experienced was a lack of morning wood. I was slightly concerned about this but I still used fin because it wasn’t a big deal to me. I think it’s subsided, because now I get morning wood again but there’s a few sides I didn’t expect. I feel like my libido has exponentially increased and the morning wood I experience is much more intense than it used to be. Is this normal? Will it subside eventually?

I have seen men who claimed a reduced sex drive in the first few weeks and found that this symptom disappeared within a month.
